+
+	<para>These are two-plane versions of the YUV 4:4:4 format. The three
+	components are separated into two sub-images or planes. The Y plane is
+	first, with each Y sample stored in one byte per pixel. For
+	<constant>V4L2_PIX_FMT_NV24</constant>, a combined CbCr plane
+	immediately follows the Y plane in memory. The CbCr plane has the same
+	width and height, in pixels, as the Y plane (and the image). Each line
+	contains one CbCr pair per pixel, with each Cb and Cr sample stored in
+	one byte. <constant>V4L2_PIX_FMT_NV42</constant> is the same except that
+	the Cb and Cr samples are swapped, the CrCb plane starts with a Cr
+	sample.</para>
+
+	<para>If the Y plane has pad bytes after each row, then the CbCr plane
+	has twice as many pad bytes after its rows.</para>

+<para>Video hardware can have various cropping, composing and scaling
+limitations. It may only scale up or down, support only discrete scaling

+cropping/composing rectangles may have to be aligned, and both the source and
+the sink may have arbitrary upper and lower size limits. Therefore, as usual,
+drivers are expected to adjust the requested parameters and return the actual
+values selected. An application can control the rounding behaviour using <link

+
+    <title>Comparison with old cropping API.</title>
+
+<para>The selection API was introduced to cope with deficiencies of previous
+<link linkend="crop"> API </link>, that was designed to control simple capture
+devices. Later the cropping API was adopted by video output drivers. The ioctls
+are used to select a part of the display were the video signal is inserted. It
+should be considered as an API abuse because the described operation is
+actually the composing.  The selection API makes a clear distinction between
+composing and cropping operations by setting the appropriate targets.  The V4L2
+API lacks any support for composing to and cropping from an image inside a
+memory buffer.  The application could configure a capture device to fill only a
+part of an image by abusing V4L2 API.  Cropping a smaller image from a larger
+one is achieved by setting the field <structfield>
+&v4l2-pix-format;::bytesperline </structfield>.  Introducing an image offsets
+could be done by modifying field <structfield> &v4l2-buffer;::m:userptr
+</structfield> before calling <constant> VIDIOC_QBUF </constant>. Those
+operations should be avoided because they are not portable (endianness), and do
+not work for macroblock and Bayer formats and mmap buffers.  The selection API
+deals with configuration of buffer cropping/composing in a clear, intuitive and
+portable way.  Next, with the selection API the concepts of the padded target
+and constraints flags are introduced.  Finally, <structname> &v4l2-crop;
+</structname> and <structname> &v4l2-cropcap; </structname> have no reserved
+fields. Therefore there is no way to extend their functionality.  The new
+<structname> &v4l2-selection; </structname> provides a lot of place for future
+extensions.  Driver developers are encouraged to implement only selection API.
+The former cropping API would be simulated using the new one. </para>

+  parameter depends on error_type specified.
+
+BIOS versions based in the ACPI 4.0 specification have limited options
+to control where the errors are injected.  Your BIOS may support an
+extension (enabled with the param_extension=1 module parameter, or
+boot command line einj.param_extension=1). This allows the address
+and mask for memory injections to be specified by the param1 and
+param2 files in apei/einj.
+
+BIOS versions using the ACPI 5.0 specification have more control over
+the target of the injection. For processor related errors (type 0x1,
+0x2 and 0x4) the APICID of the target should be provided using the
+param1 file in apei/einj. For memory errors (type 0x8, 0x10 and 0x20)
+the address is set using param1 with a mask in param2 (0x0 is equivalent
+to all ones). For PCI express errors (type 0x40, 0x80 and 0x100) the
+segment, bus, device and function are specified using param1:

+	| segment |   bus  | device | function | reserved |
+	+-------------------------------------------------+
+
+An ACPI 5.0 BIOS may also allow vendor specific errors to be injected.
+In this case a file named vendor will contain identifying information
+from the BIOS that hopefully will allow an application wishing to use
+the vendor specific extension to tell that they are running on a BIOS
+that supports it. All vendor extensions have the 0x80000000 bit set in
+error_type. A file vendor_flags controls the interpretation of param1
+and param2 (1 = PROCESSOR, 2 = MEMORY, 4 = PCI). See your BIOS vendor
+documentation for details (and expect changes to this API if vendors
+creativity in using this feature expands beyond our expectations).
+
+Example:
+# cd /sys/kernel/debug/apei/einj
+# cat available_error_type		# See which errors can be injected
+0x00000002	Processor Uncorrectable non-fatal
+0x00000008	Memory Correctable
+0x00000010	Memory Uncorrectable non-fatal
+# echo 0x12345000 > param1		# Set memory address for injection
+# echo 0xfffffffffffff000 > param2	# Mask - anywhere in this page
+# echo 0x8 > error_type			# Choose correctable memory error

+			The Frame Buffer Device API
+			---------------------------
+
+Last revised: June 21, 2011
+
+
+0. Introduction
+---------------
+
+This document describes the frame buffer API used by applications to interact
+with frame buffer devices. In-kernel APIs between device drivers and the frame
+buffer core are not described.
+
+Due to a lack of documentation in the original frame buffer API, drivers
+behaviours differ in subtle (and not so subtle) ways. This document describes
+the recommended API implementation, but applications should be prepared to
+deal with different behaviours.
+
+
+1. Capabilities
+---------------
+
+Device and driver capabilities are reported in the fixed screen information
+capabilities field.
+
+struct fb_fix_screeninfo {
+	...
+	__u16 capabilities;		/* see FB_CAP_*			*/
+	...
+};
+
+Application should use those capabilities to find out what features they can
+expect from the device and driver.
+
+- FB_CAP_FOURCC
+
+The driver supports the four character code (FOURCC) based format setting API.
+When supported, formats are configured using a FOURCC instead of manually
+specifying color components layout.
+
+
+2. Types and visuals
+--------------------
+
+Pixels are stored in memory in hardware-dependent formats. Applications need
+to be aware of the pixel storage format in order to write image data to the
+frame buffer memory in the format expected by the hardware.
+
+Formats are described by frame buffer types and visuals. Some visuals require
+additional information, which are stored in the variable screen information
+bits_per_pixel, grayscale, red, green, blue and transp fields.
+
+Visuals describe how color information is encoded and assembled to create
+macropixels. Types describe how macropixels are stored in memory. The following
+types and visuals are supported.
+
+- FB_TYPE_PACKED_PIXELS
+
+Macropixels are stored contiguously in a single plane. If the number of bits
+per macropixel is not a multiple of 8, whether macropixels are padded to the
+next multiple of 8 bits or packed together into bytes depends on the visual.
+
+Padding at end of lines may be present and is then reported through the fixed
+screen information line_length field.
+
+- FB_TYPE_PLANES
+
+Macropixels are split across multiple planes. The number of planes is equal to
+the number of bits per macropixel, with plane i'th storing i'th bit from all
+macropixels.
+
+Planes are located contiguously in memory.
+
+- FB_TYPE_INTERLEAVED_PLANES
+
+Macropixels are split across multiple planes. The number of planes is equal to
+the number of bits per macropixel, with plane i'th storing i'th bit from all
+macropixels.
+
+Planes are interleaved in memory. The interleave factor, defined as the
+distance in bytes between the beginning of two consecutive interleaved blocks
+belonging to different planes, is stored in the fixed screen information
+type_aux field.
+
+- FB_TYPE_FOURCC
+
+Macropixels are stored in memory as described by the format FOURCC identifier
+stored in the variable screen information grayscale field.
+
+- FB_VISUAL_MONO01
+
+Pixels are black or white and stored on a number of bits (typically one)
+specified by the variable screen information bpp field.
+
+Black pixels are represented by all bits set to 1 and white pixels by all bits
+set to 0. When the number of bits per pixel is smaller than 8, several pixels
+are packed together in a byte.
+
+FB_VISUAL_MONO01 is currently used with FB_TYPE_PACKED_PIXELS only.
+
+- FB_VISUAL_MONO10
+
+Pixels are black or white and stored on a number of bits (typically one)
+specified by the variable screen information bpp field.
+
+Black pixels are represented by all bits set to 0 and white pixels by all bits
+set to 1. When the number of bits per pixel is smaller than 8, several pixels
+are packed together in a byte.
+
+FB_VISUAL_MONO01 is currently used with FB_TYPE_PACKED_PIXELS only.
+
+- FB_VISUAL_TRUECOLOR
+
+Pixels are broken into red, green and blue components, and each component
+indexes a read-only lookup table for the corresponding value. Lookup tables
+are device-dependent, and provide linear or non-linear ramps.
+
+Each component is stored in a macropixel according to the variable screen
+information red, green, blue and transp fields.
+
+- FB_VISUAL_PSEUDOCOLOR and FB_VISUAL_STATIC_PSEUDOCOLOR
+
+Pixel values are encoded as indices into a colormap that stores red, green and
+blue components. The colormap is read-only for FB_VISUAL_STATIC_PSEUDOCOLOR
+and read-write for FB_VISUAL_PSEUDOCOLOR.
+
+Each pixel value is stored in the number of bits reported by the variable
+screen information bits_per_pixel field.
+
+- FB_VISUAL_DIRECTCOLOR
+
+Pixels are broken into red, green and blue components, and each component
+indexes a programmable lookup table for the corresponding value.
+
+Each component is stored in a macropixel according to the variable screen
+information red, green, blue and transp fields.
+
+- FB_VISUAL_FOURCC
+
+Pixels are encoded and  interpreted as described by the format FOURCC
+identifier stored in the variable screen information grayscale field.
+
+
+3. Screen information
+---------------------
+
+Screen information are queried by applications using the FBIOGET_FSCREENINFO
+and FBIOGET_VSCREENINFO ioctls. Those ioctls take a pointer to a
+fb_fix_screeninfo and fb_var_screeninfo structure respectively.
+
+struct fb_fix_screeninfo stores device independent unchangeable information
+about the frame buffer device and the current format. Those information can't
+be directly modified by applications, but can be changed by the driver when an
+application modifies the format.
+
+struct fb_fix_screeninfo {
+	char id[16];			/* identification string eg "TT Builtin" */
+	unsigned long smem_start;	/* Start of frame buffer mem */
+					/* (physical address) */
+	__u32 smem_len;			/* Length of frame buffer mem */
+	__u32 type;			/* see FB_TYPE_*		*/
+	__u32 type_aux;			/* Interleave for interleaved Planes */
+	__u32 visual;			/* see FB_VISUAL_*		*/
+	__u16 xpanstep;			/* zero if no hardware panning  */
+	__u16 ypanstep;			/* zero if no hardware panning  */
+	__u16 ywrapstep;		/* zero if no hardware ywrap    */
+	__u32 line_length;		/* length of a line in bytes    */
+	unsigned long mmio_start;	/* Start of Memory Mapped I/O   */
+					/* (physical address) */
+	__u32 mmio_len;			/* Length of Memory Mapped I/O  */
+	__u32 accel;			/* Indicate to driver which	*/
+					/*  specific chip/card we have	*/
+	__u16 capabilities;		/* see FB_CAP_*			*/
+	__u16 reserved[2];		/* Reserved for future compatibility */
+};
+
+struct fb_var_screeninfo stores device independent changeable information
+about a frame buffer device, its current format and video mode, as well as
+other miscellaneous parameters.
+
+struct fb_var_screeninfo {
+	__u32 xres;			/* visible resolution		*/
+	__u32 yres;
+	__u32 xres_virtual;		/* virtual resolution		*/
+	__u32 yres_virtual;
+	__u32 xoffset;			/* offset from virtual to visible */
+	__u32 yoffset;			/* resolution			*/
+
+	__u32 bits_per_pixel;		/* guess what			*/
+	__u32 grayscale;		/* 0 = color, 1 = grayscale,	*/
+					/* >1 = FOURCC			*/
+	struct fb_bitfield red;		/* bitfield in fb mem if true color, */
+	struct fb_bitfield green;	/* else only length is significant */
+	struct fb_bitfield blue;
+	struct fb_bitfield transp;	/* transparency			*/
+
+	__u32 nonstd;			/* != 0 Non standard pixel format */
+
+	__u32 activate;			/* see FB_ACTIVATE_*		*/
+
+	__u32 height;			/* height of picture in mm    */
+	__u32 width;			/* width of picture in mm     */
+
+	__u32 accel_flags;		/* (OBSOLETE) see fb_info.flags */
+
+	/* Timing: All values in pixclocks, except pixclock (of course) */
+	__u32 pixclock;			/* pixel clock in ps (pico seconds) */
+	__u32 left_margin;		/* time from sync to picture	*/
+	__u32 right_margin;		/* time from picture to sync	*/
+	__u32 upper_margin;		/* time from sync to picture	*/
+	__u32 lower_margin;
+	__u32 hsync_len;		/* length of horizontal sync	*/
+	__u32 vsync_len;		/* length of vertical sync	*/
+	__u32 sync;			/* see FB_SYNC_*		*/
+	__u32 vmode;			/* see FB_VMODE_*		*/
+	__u32 rotate;			/* angle we rotate counter clockwise */
+	__u32 colorspace;		/* colorspace for FOURCC-based modes */
+	__u32 reserved[4];		/* Reserved for future compatibility */
+};
+
+To modify variable information, applications call the FBIOPUT_VSCREENINFO
+ioctl with a pointer to a fb_var_screeninfo structure. If the call is
+successful, the driver will update the fixed screen information accordingly.
+
+Instead of filling the complete fb_var_screeninfo structure manually,
+applications should call the FBIOGET_VSCREENINFO ioctl and modify only the
+fields they care about.
+
+
+4. Format configuration
+-----------------------
+
+Frame buffer devices offer two ways to configure the frame buffer format: the
+legacy API and the FOURCC-based API.
+
+
+The legacy API has been the only frame buffer format configuration API for a
+long time and is thus widely used by application. It is the recommended API
+for applications when using RGB and grayscale formats, as well as legacy
+non-standard formats.
+
+To select a format, applications set the fb_var_screeninfo bits_per_pixel field
+to the desired frame buffer depth. Values up to 8 will usually map to
+monochrome, grayscale or pseudocolor visuals, although this is not required.
+
+- For grayscale formats, applications set the grayscale field to one. The red,
+  blue, green and transp fields must be set to 0 by applications and ignored by
+  drivers. Drivers must fill the red, blue and green offsets to 0 and lengths
+  to the bits_per_pixel value.
+
+- For pseudocolor formats, applications set the grayscale field to zero. The
+  red, blue, green and transp fields must be set to 0 by applications and
+  ignored by drivers. Drivers must fill the red, blue and green offsets to 0
+  and lengths to the bits_per_pixel value.
+
+- For truecolor and directcolor formats, applications set the grayscale field
+  to zero, and the red, blue, green and transp fields to describe the layout of
+  color components in memory.
+
+struct fb_bitfield {
+	__u32 offset;			/* beginning of bitfield	*/
+	__u32 length;			/* length of bitfield		*/
+	__u32 msb_right;		/* != 0 : Most significant bit is */
+					/* right */
+};
+
+  Pixel values are bits_per_pixel wide and are split in non-overlapping red,
+  green, blue and alpha (transparency) components. Location and size of each
+  component in the pixel value are described by the fb_bitfield offset and
+  length fields. Offset are computed from the right.
+
+  Pixels are always stored in an integer number of bytes. If the number of
+  bits per pixel is not a multiple of 8, pixel values are padded to the next
+  multiple of 8 bits.
+
+Upon successful format configuration, drivers update the fb_fix_screeninfo
+type, visual and line_length fields depending on the selected format.
+
+
+The FOURCC-based API replaces format descriptions by four character codes
+(FOURCC). FOURCCs are abstract identifiers that uniquely define a format
+without explicitly describing it. This is the only API that supports YUV
+formats. Drivers are also encouraged to implement the FOURCC-based API for RGB
+and grayscale formats.
+
+Drivers that support the FOURCC-based API report this capability by setting
+the FB_CAP_FOURCC bit in the fb_fix_screeninfo capabilities field.
+
+FOURCC definitions are located in the linux/videodev2.h header. However, and
+despite starting with the V4L2_PIX_FMT_prefix, they are not restricted to V4L2
+and don't require usage of the V4L2 subsystem. FOURCC documentation is
+available in Documentation/DocBook/v4l/pixfmt.xml.
+
+To select a format, applications set the grayscale field to the desired FOURCC.
+For YUV formats, they should also select the appropriate colorspace by setting
+the colorspace field to one of the colorspaces listed in linux/videodev2.h and
+documented in Documentation/DocBook/v4l/colorspaces.xml.
+
+The red, green, blue and transp fields are not used with the FOURCC-based API.
+For forward compatibility reasons applications must zero those fields, and
+drivers must ignore them. Values other than 0 may get a meaning in future
+extensions.
+
+Upon successful format configuration, drivers update the fb_fix_screeninfo
+type, visual and line_length fields depending on the selected format. The type
+and visual fields are set to FB_TYPE_FOURCC and FB_VISUAL_FOURCC respectively.

+
+Fault Injection
+===============
+Fault injection is a method for forcing errors that may not normally occur, or
+may be difficult to reproduce.  Forcing these errors in a controlled environment
+can help the developer find and fix bugs before their code is shipped in a
+production system.  Injecting an error on the Linux NFS server will allow us to
+observe how the client reacts and if it manages to recover its state correctly.
+
+NFSD_FAULT_INJECTION must be selected when configuring the kernel to use this
+feature.
+
+
+Using Fault Injection
+=====================
+On the client, mount the fault injection server through NFS v4.0+ and do some
+work over NFS (open files, take locks, ...).
+
+On the server, mount the debugfs filesystem to <debug_dir> and ls
+<debug_dir>/nfsd.  This will show a list of files that will be used for
+injecting faults on the NFS server.  As root, write a number n to the file
+corresponding to the action you want the server to take.  The server will then
+process the first n items it finds.  So if you want to forget 5 locks, echo '5'
+to <debug_dir>/nfsd/forget_locks.  A value of 0 will tell the server to forget
+all corresponding items.  A log message will be created containing the number
+of items forgotten (check dmesg).
+
+Go back to work on the client and check if the client recovered from the error
+correctly.
+
+
+Available Faults
+================
+forget_clients:
+     The NFS server keeps a list of clients that have placed a mount call.  If
+     this list is cleared, the server will have no knowledge of who the client
+     is, forcing the client to reauthenticate with the server.
+
+forget_openowners:
+     The NFS server keeps a list of what files are currently opened and who
+     they were opened by.  Clearing this list will force the client to reopen
+     its files.
+
+forget_locks:
+     The NFS server keeps a list of what files are currently locked in the VFS.
+     Clearing this list will force the client to reclaim its locks (files are
+     unlocked through the VFS as they are cleared from this list).
+
+forget_delegations:
+     A delegation is used to assure the client that a file, or part of a file,
+     has not changed since the delegation was awarded.  Clearing this list will
+     force the client to reaquire its delegation before accessing the file
+     again.
+
+recall_delegations:
+     Delegations can be recalled by the server when another client attempts to
+     access a file.  This test will notify the client that its delegation has
+     been revoked, forcing the client to reaquire the delegation before using
+     the file again.
+
+
+tools/nfs/inject_faults.sh script
+=================================
+This script has been created to ease the fault injection process.  This script
+will detect the mounted debugfs directory and write to the files located there
+based on the arguments passed by the user.  For example, running
+`inject_faults.sh forget_locks 1` as root will instruct the server to forget
+one lock.  Running `inject_faults forget_locks` will instruct the server to
+forgetall locks.

-Differences from the Spec
-=========================
-
-There are a few places where the framework acts slightly differently from the
-V4L2 Specification. Those differences are described in this section. We will
-have to see whether we need to adjust the spec or not.
-
-1) It is no longer required to have all controls contained in a
-v4l2_ext_control array be from the same control class. The framework will be
-able to handle any type of control in the array. You need to set ctrl_class
-to 0 in order to enable this. If ctrl_class is non-zero, then it will still
-check that all controls belong to that control class.
-
-If you set ctrl_class to 0 and count to 0, then it will only return an error
-if there are no controls at all.
-
-2) Clarified the way error_idx works. For get and set it will be equal to
-count if nothing was done yet. If it is less than count then only the controls
-up to error_idx-1 were successfully applied.
-
-

 also waits in the code, then you should do the same to allow other processes
 to access the device node while the first process is waiting for something.
 
+In the case of videobuf2 you will need to implement the wait_prepare and
+wait_finish callbacks to unlock/lock if applicable. In particular, if you use

+wait_prepare and wait_finish.

 The implementation of a hotplug disconnect should also take the lock before
 calling v4l2_device_disconnect.

+	  supported by InfiniBand and by iWarp network hardware. More
+	  information about the SRP protocol can be found on the website

  * Video queues is initialized by uvc_queue_init(). The function performs
  * basic initialization of the uvc_video_queue struct and never fails.
  *
- * Video buffer allocation and freeing are performed by uvc_alloc_buffers and
- * uvc_free_buffers respectively. The former acquires the video queue lock,
- * while the later must be called with the lock held (so that allocation can
- * free previously allocated buffers). Trying to free buffers that are mapped
- * to user space will return -EBUSY.
- *
- * Video buffers are managed using two queues. However, unlike most USB video
- * drivers that use an in queue and an out queue, we use a main queue to hold
- * all queued buffers (both 'empty' and 'done' buffers), and an irq queue to
- * hold empty buffers. This design (copied from video-buf) minimizes locking
- * in interrupt, as only one queue is shared between interrupt and user
- * contexts.
- *
- * Use cases
- * ---------
- *
- * Unless stated otherwise, all operations that modify the irq buffers queue
- * are protected by the irq spinlock.
- *
- * 1. The user queues the buffers, starts streaming and dequeues a buffer.
- *
- *    The buffers are added to the main and irq queues. Both operations are
- *    protected by the queue lock, and the later is protected by the irq
- *    spinlock as well.
- *
- *    The completion handler fetches a buffer from the irq queue and fills it
- *    with video data. If no buffer is available (irq queue empty), the handler
- *    returns immediately.
- *
- *    When the buffer is full, the completion handler removes it from the irq
- *    queue, marks it as done (UVC_BUF_STATE_DONE) and wakes its wait queue.
- *    At that point, any process waiting on the buffer will be woken up. If a
- *    process tries to dequeue a buffer after it has been marked done, the
- *    dequeing will succeed immediately.
- *
- * 2. Buffers are queued, user is waiting on a buffer and the device gets
- *    disconnected.
- *
- *    When the device is disconnected, the kernel calls the completion handler
- *    with an appropriate status code. The handler marks all buffers in the
- *    irq queue as being erroneous (UVC_BUF_STATE_ERROR) and wakes them up so
- *    that any process waiting on a buffer gets woken up.
- *
- *    Waking up up the first buffer on the irq list is not enough, as the
- *    process waiting on the buffer might restart the dequeue operation
- *    immediately.
- *
+ * Video buffers are managed by videobuf2. The driver uses a mutex to protect
+ * the videobuf2 queue operations by serializing calls to videobuf2 and a
+ * spinlock to protect the IRQ queue that holds the buffers to be processed by
+ * the driver.

+ *
+ * The relationship between the device clock and the host clock isn't known.
+ * However, the device and the host share the common USB SOF clock which can be
+ * used to recover that relationship.
+ *
+ * The relationship between the device clock and the USB SOF clock is considered
+ * to be linear over the clock samples sliding window and is given by
+ *
+ * SOF = m * PTS + p
+ *
+ * Several methods to compute the slope (m) and intercept (p) can be used. As
+ * the clock drift should be small compared to the sliding window size, we
+ * assume that the line that goes through the points at both ends of the window
+ * is a good approximation. Naming those points P1 and P2, we get
+ *
+ * SOF = (SOF2 - SOF1) / (STC2 - STC1) * PTS
+ *     + (SOF1 * STC2 - SOF2 * STC1) / (STC2 - STC1)
+ *
+ * or
+ *
+ * SOF = ((SOF2 - SOF1) * PTS + SOF1 * STC2 - SOF2 * STC1) / (STC2 - STC1)   (1)
+ *
+ * to avoid loosing precision in the division. Similarly, the host timestamp is
+ * computed with
+ *
+ * TS = ((TS2 - TS1) * PTS + TS1 * SOF2 - TS2 * SOF1) / (SOF2 - SOF1)	     (2)
+ *
+ * SOF values are coded on 11 bits by USB. We extend their precision with 16
+ * decimal bits, leading to a 11.16 coding.
+ *
+ * TODO: To avoid surprises with device clock values, PTS/STC timestamps should
+ * be normalized using the nominal device clock frequency reported through the
+ * UVC descriptors.
+ *
+ * Both the PTS/STC and SOF counters roll over, after a fixed but device
+ * specific amount of time for PTS/STC and after 2048ms for SOF. As long as the
+ * sliding window size is smaller than the rollover period, differences computed
+ * on unsigned integers will produce the correct result. However, the p term in
+ * the linear relations will be miscomputed.
+ *
+ * To fix the issue, we subtract a constant from the PTS and STC values to bring
+ * PTS to half the 32 bit STC range. The sliding window STC values then fit into
+ * the 32 bit range without any rollover.
+ *
+ * Similarly, we add 2048 to the device SOF values to make sure that the SOF
+ * computed by (1) will never be smaller than 0. This offset is then compensated
+ * by adding 2048 to the SOF values used in (2). However, this doesn't prevent
+ * rollovers between (1) and (2): the SOF value computed by (1) can be slightly
+ * lower than 4096, and the host SOF counters can have rolled over to 2048. This
+ * case is handled by subtracting 2048 from the SOF value if it exceeds the host
+ * SOF value at the end of the sliding window.
+ *
+ * Finally we subtract a constant from the host timestamps to bring the first
+ * timestamp of the sliding window to 1s.

+/*
+ * The MMCIF driver is now processing MMC requests asynchronously, according
+ * to the Linux MMC API requirement.
+ *
+ * The MMCIF driver processes MMC requests in up to 3 stages: command, optional
+ * data, and optional stop. To achieve asynchronous processing each of these
+ * stages is split into two halves: a top and a bottom half. The top half
+ * initialises the hardware, installs a timeout handler to handle completion
+ * timeouts, and returns. In case of the command stage this immediately returns
+ * control to the caller, leaving all further processing to run asynchronously.
+ * All further request processing is performed by the bottom halves.
+ *
+ * The bottom half further consists of a "hard" IRQ handler, an IRQ handler
+ * thread, a DMA completion callback, if DMA is used, a timeout work, and
+ * request- and stage-specific handler methods.
+ *
+ * Each bottom half run begins with either a hardware interrupt, a DMA callback
+ * invocation, or a timeout work run. In case of an error or a successful
+ * processing completion, the MMC core is informed and the request processing is
+ * finished. In case processing has to continue, i.e., if data has to be read
+ * from or written to the card, or if a stop command has to be sent, the next
+ * top half is called, which performs the necessary hardware handling and
+ * reschedules the timeout work. This returns the driver state machine into the
+ * bottom half waiting state.

       - a scanline is 63.5 µs long, of which 53.5 µs are visible.  This is about
-        736 visible 70 ns pixels per line.
+	736 visible 70 ns pixels per line.
       - we have 525 scanlines, of which 485 are visible (interlaced); after
-        rounding this becomes 484.
+	rounding this becomes 484.
 
    Thus if you want a PAL compatible display, you have to do the following:
 
       - set the FB_SYNC_BROADCAST flag to indicate that standard broadcast
-        timings are to be used.
-      - make sure upper_margin+yres+lower_margin+vsync_len = 625 for an
-        interlaced, 312 for a non-interlaced and 156 for a doublescanned
-        display.
-      - make sure left_margin+xres+right_margin+hsync_len = 1816 for a SHRES,
-        908 for a HIRES and 454 for a LORES display.
+	timings are to be used.
+      - make sure upper_margin + yres + lower_margin + vsync_len = 625 for an
+	interlaced, 312 for a non-interlaced and 156 for a doublescanned
+	display.
+      - make sure left_margin + xres + right_margin + hsync_len = 1816 for a
+	SHRES, 908 for a HIRES and 454 for a LORES display.
       - the left visible part begins at 360 (SHRES; HIRES:180, LORES:90),
-        left_margin+2*hsync_len must be greater or equal.
+	left_margin + 2 * hsync_len must be greater or equal.
       - the upper visible part begins at 48 (interlaced; non-interlaced:24,
-        doublescanned:12), upper_margin+2*vsync_len must be greater or equal.
+	doublescanned:12), upper_margin + 2 * vsync_len must be greater or
+	equal.
       - ami_encode_var() calculates margins with a hsync of 5320 ns and a vsync
-        of 4 scanlines
+	of 4 scanlines
 
    The settings for a NTSC compatible display are straightforward.

+/*
+ * This module can be used to catch cases when the btrfs kernel
+ * code executes write requests to the disk that bring the file
+ * system in an inconsistent state. In such a state, a power-loss
+ * or kernel panic event would cause that the data on disk is
+ * lost or at least damaged.
+ *
+ * Code is added that examines all block write requests during
+ * runtime (including writes of the super block). Three rules
+ * are verified and an error is printed on violation of the
+ * rules:
+ * 1. It is not allowed to write a disk block which is
+ *    currently referenced by the super block (either directly
+ *    or indirectly).
+ * 2. When a super block is written, it is verified that all
+ *    referenced (directly or indirectly) blocks fulfill the
+ *    following requirements:
+ *    2a. All referenced blocks have either been present when
+ *        the file system was mounted, (i.e., they have been
+ *        referenced by the super block) or they have been
+ *        written since then and the write completion callback
+ *        was called and a FLUSH request to the device where
+ *        these blocks are located was received and completed.
+ *    2b. All referenced blocks need to have a generation
+ *        number which is equal to the parent's number.
+ *
+ * One issue that was found using this module was that the log
+ * tree on disk became temporarily corrupted because disk blocks
+ * that had been in use for the log tree had been freed and
+ * reused too early, while being referenced by the written super
+ * block.
+ *
+ * The search term in the kernel log that can be used to filter
+ * on the existence of detected integrity issues is
+ * "btrfs: attempt".
+ *
+ * The integrity check is enabled via mount options. These
+ * mount options are only supported if the integrity check
+ * tool is compiled by defining BTRFS_FS_CHECK_INTEGRITY.
+ *
+ * Example #1, apply integrity checks to all metadata:
+ * mount /dev/sdb1 /mnt -o check_int
+ *
+ * Example #2, apply integrity checks to all metadata and
+ * to data extents:
+ * mount /dev/sdb1 /mnt -o check_int_data
+ *
+ * Example #3, apply integrity checks to all metadata and dump
+ * the tree that the super block references to kernel messages
+ * each time after a super block was written:
+ * mount /dev/sdb1 /mnt -o check_int,check_int_print_mask=263
+ *
+ * If the integrity check tool is included and activated in
+ * the mount options, plenty of kernel memory is used, and
+ * plenty of additional CPU cycles are spent. Enabling this
+ * functionality is not intended for normal use. In most
+ * cases, unless you are a btrfs developer who needs to verify
+ * the integrity of (super)-block write requests, do not
+ * enable the config option BTRFS_FS_CHECK_INTEGRITY to
+ * include and compile the integrity check tool.

+ *
+ * recover_done() provides a new lockspace generation number each time it

+ * When recover_prep() is called, it sets BLOCK_LOCKS and sets

+ * 15. gfs2_control checks if recover_block == recover_start (step 3 occured
+ *     again) then do nothing, otherwise if recover_start > recover_block

+ *
+ * - parallel recovery steps across all nodes
+ *
+ * All nodes attempt to update the control_lock lvb with the new generation
+ * number and jid bits, but only the first to get the control_lock EX will
+ * do so; others will see that it's already done (lvb already contains new
+ * generation number.)
+ *
+ * . All nodes get the same recover_prep/recover_slot/recover_done callbacks
+ * . All nodes attempt to set control_lock lvb gen + bits for the new gen
+ * . One node gets control_lock first and writes the lvb, others see it's done
+ * . All nodes attempt to recover jids for which they see control_lock bits set
+ * . One node succeeds for a jid, and that one clears the jid bit in the lvb
+ * . All nodes will eventually see all lvb bits clear and unblock locks
+ *
+ * - is there a problem with clearing an lvb bit that should be set
+ *   and missing a journal recovery?
+ *
+ * 1. jid fails
+ * 2. lvb bit set for step 1
+ * 3. jid recovered for step 1
+ * 4. jid taken again (new mount)
+ * 5. jid fails (for step 4)
+ * 6. lvb bit set for step 5 (will already be set)
+ * 7. lvb bit cleared for step 3
+ *
+ * This is not a problem because the failure in step 5 does not
+ * require recovery, because the mount in step 4 could not have
+ * progressed far enough to unblock locks and access the fs.  The
+ * control_mount() function waits for all recoveries to be complete
+ * for the latest lockspace generation before ever unblocking locks
+ * and returning.  The mount in step 4 waits until the recovery in
+ * step 1 is done.
+ *
+ * - special case of first mounter: first node to mount the fs
+ *
+ * The first node to mount a gfs2 fs needs to check all the journals
+ * and recover any that need recovery before other nodes are allowed
+ * to mount the fs.  (Others may begin mounting, but they must wait
+ * for the first mounter to be done before taking locks on the fs
+ * or accessing the fs.)  This has two parts:
+ *
+ * 1. The mounted_lock tells a node it's the first to mount the fs.
+ * Each node holds the mounted_lock in PR while it's mounted.

+ * the first mount recovery, blocking mounts from other nodes, then demotes
+ * control_lock to NL when it's done (others_may_mount/first_done),

+ * control_lock EX->NL, write lvb generation

+ * An io_cq (icq) is association between an io_context (ioc) and a
+ * request_queue (q).  This is used by elevators which need to track
+ * information per ioc - q pair.
+ *
+ * Elevator can request use of icq by setting elevator_type->icq_size and
+ * ->icq_align.  Both size and align must be larger than that of struct
+ * io_cq and elevator can use the tail area for private information.  The
+ * recommended way to do this is defining a struct which contains io_cq as
+ * the first member followed by private members and using its size and
+ * align.  For example,
+ *
+ *	struct snail_io_cq {
+ *		struct io_cq	icq;
+ *		int		poke_snail;
+ *		int		feed_snail;
+ *	};
+ *
+ *	struct elevator_type snail_elv_type {
+ *		.ops =		{ ... },
+ *		.icq_size =	sizeof(struct snail_io_cq),
+ *		.icq_align =	__alignof__(struct snail_io_cq),
+ *		...
+ *	};
+ *
+ * If icq_size is set, block core will manage icq's.  All requests will
+ * have its ->elv.icq field set before elevator_ops->elevator_set_req_fn()
+ * is called and be holding a reference to the associated io_context.
+ *
+ * Whenever a new icq is created, elevator_ops->elevator_init_icq_fn() is
+ * called and, on destruction, ->elevator_exit_icq_fn().  Both functions
+ * are called with both the associated io_context and queue locks held.
+ *
+ * Elevator is allowed to lookup icq using ioc_lookup_icq() while holding
+ * queue lock but the returned icq is valid only until the queue lock is
+ * released.  Elevators can not and should not try to create or destroy
+ * icq's.

+ *
+ * - ioc->icq_list and icq->ioc_node are protected by ioc lock.
+ *   q->icq_list and icq->q_node by q lock.
+ *
+ * - ioc->icq_tree and ioc->icq_hint are protected by ioc lock, while icq
+ *   itself is protected by q lock.  However, both the indexes and icq
+ *   itself are also RCU managed and lookup can be performed holding only
+ *   the q lock.
+ *
+ * - icq's are not reference counted.  They are destroyed when either the
+ *   ioc or q goes away.  Each request with icq set holds an extra
+ *   reference to ioc to ensure it stays until the request is completed.
+ *
+ * - Linking and unlinking icq's are performed while holding both ioc and q
+ *   locks.  Due to the lock ordering, q exit is simple but ioc exit
+ *   requires reverse-order double lock dance.

+ * The backend can optionally provide three extra XenBus attributes to

+ * 'discard-aligment' - Devices that support discard functionality may
+ * internally allocate space in units that are bigger than the exported
+ * logical block size. The discard-alignment parameter indicates how many bytes
+ * the beginning of the partition is offset from the internal allocation unit's
+ * natural alignment.
+ * 'discard-granularity'  - Devices that support discard functionality may
+ * internally allocate space using units that are bigger than the logical block
+ * size. The discard-granularity parameter indicates the size of the internal
+ * allocation unit in bytes if reported by the device. Otherwise the
+ * discard-granularity will be set to match the device's physical block size.
+ * 'discard-secure' - All copies of the discarded sectors (potentially created
+ * by garbage collection) must also be erased.  To use this feature, the flag
+ * BLKIF_DISCARD_SECURE must be set in the blkif_request_trim.

+/// See Documentation/driver-model/devres.txt for more information.
+///
+/// A difficulty of detecting this problem is that the standard freeing
+/// function might be called from a different function than the one
+/// containing the allocation function.  It is thus necessary to make the
+/// connection between the allocation function and the freeing function.
+/// Here this is done using the specific argument text, which is prone to
+/// false positives.  There is no rule for the request_region and
+/// request_mem_region variants because this heuristic seems to be a bit
+/// less reliable in these cases.
