+ * BFI_IOIM_STS_TIMEDOUT : IO timedout and ABTS/RRQ is happening

+ * - io-tag cannot be reused yet.
+ *
+ * BFI_IOIM_STS_SQER_NEEDED : Firmware could not recover the IO
+ * with sequence level error

+ * this IO with a different IO tag
+ * - io-tag cannot be used yet.
+ *
+ * BFI_IOIM_STS_NEXUS_ABORT : Second Level Error Recovery from host

+ * - io-tag cannot be used yet.
+ *
+ * BFI_IOIM_STS_UNDERRUN : IO completed with SCSI status good,

+ * ex. SCSI INQUIRY where transferred
+ * data length and residue count in FCP
+ * response accounts for total fcp-dl
+ * - io-tag can be reused.

+ * TAPE IOs where blocks can of unequal

+ * - io-tag can be reused.
+ *
+ * BFI_IOIM_STS_RES_FREE : Firmware has completed using io-tag
+ * during abort process
+ * - io-tag can be reused.
+ *
+ * BFI_IOIM_STS_PROTO_ERR : Firmware detected a protocol error.
+ * ex target sent more data than
+ * requested, or there was data frame
+ * loss and other reasons
+ * - io-tag cannot be used yet.
+ *
+ * BFI_IOIM_STS_DIF_ERR : Firwmare detected DIF error. ex: DIF
+ * CRC err or Ref Tag err or App tag err.
+ * - io-tag can be reused.
+ *
+ * BFA_IOIM_STS_TSK_MGT_ABORT : IO was aborted because of Task

- Cowloop is a "copy-on-write" pseudo block driver. It can be
- stacked on top of a "real" block driver, and catches all write
- operations on their way from the file systems layer above to
- the real driver below, effectively shielding the lower driver
- from those write accesses. The requests are then diverted to
- an ordinary file, located somewhere else (configurable). Later
- read requests are checked to see whether they can be serviced
- by the "real" block driver below, or must be pulled in from
- the diverted location. More information and userspace tools to
- use the driver are on the project's website

-** COWLOOP block device driver (2.6 kernel compliant)
-** =======================================================================
-** Read-write loop-driver with copy-on-write functionality.
-**
-** Synopsis:
-**
-** modprobe cowloop [maxcows=..] [rdofile=..... cowfile=.... [option=r]]
-**
-** Definition of number of configured cowdevices:
-** maxcows= number of configured cowdevices (default: 16)
-** (do not confuse this with MAXCOWS: absolute maximum as compiled)
-**
-** One pair of filenames can be supplied during insmod/modprobe to open
-** the first cowdevice:
-** rdofile= read-only file (or filesystem)
-** cowfile= storage-space for modified blocks of read-only file(system)
-** option=r repair cowfile automatically if it appears to be dirty
-**
-** Other cowdevices can be activated via the command "cowdev"
-** whenever the cowloop-driver is loaded.
-**
-** The read-only file may be of type 'regular' or 'block-device'.
-**
-** The cowfile must be of type 'regular'.
-** If an existing regular file is used as cowfile, its contents will be
-** used again for the current read-only file. When the cowfile has not been
-** closed properly during a previous session (i.e. rmmod cowloop), the
-** cowloop-driver refuses to open it unless the parameter "option=r" is
-** specified.
-**
-** Layout of cowfile:
-**
-** +-----------------------------+
-** | cow head block | MAPUNIT bytes
-** |-----------------------------|
-** | | MAPUNIT bytes
-** |--- ---|
-** | | MAPUNIT bytes
-** |--- ---|
-** | used-block bitmap | MAPUNIT bytes
-** |-----------------------------|
-** | gap to align start-offset |
-** | to 4K multiple |
-** |-----------------------------| <---- start-offset cow blocks
-** | |
-** | written cow blocks | MAPUNIT bytes
-** | ..... |
-**
-** cowhead block:
-** - contains general info about the rdofile which is related
-** to this cowfile
-**
-** used-block bitmap:
-** - contains one bit per block with a size of MAPUNIT bytes
-** - bit-value '1' = block has been written on cow
-** '0' = block unused on cow
-** - total bitmap rounded to multiples of MAPUNIT

-**
-** 200405 Ported to kernel-version 2.6 Hendrik-Jan Thomassen
-** 200405 Added cowhead to cowfile to garantee
-** consistency with read-only file Gerlof Langeveld
-** 200405 Postponed flushing of bitmaps to improve
-** performance. Gerlof Langeveld
-** 200405 Inline recovery for dirty cowfiles. Gerlof Langeveld
-** 200502 Redesign to support more cowdevices. Gerlof Langeveld
-** 200502 Support devices/file > 2 Gbytes. Gerlof Langeveld
-** 200507 Check for free space to expand cowfile. Gerlof Langeveld
-** 200902 Upgrade for kernel 2.6.28 Hendrik-Jan Thomassen
-**
-** Inspired by
-** loop.c by Theodore Ts'o and
-** cloop.c by Paul `Rusty' Russell & Klaus Knopper.
-**
-** Design-considerations:
-**
-** For the first experiments with the cowloop-driver, the request-queue
-** made use of the do_generic_file_read() which worked fine except
-** in combination with the cloop-driver; that combination
-** resulted in a non-interruptible hangup of the system during
-** heavy load. Other experiments using the `make_request' interface also
-** resulted in unpredictable system hangups (with proper use of spinlocks).
-**
-** To overcome these problems, the cowloop-driver starts a kernel-thread
-** for every active cowdevice.
-** All read- and write-request on the read-only file and copy-on-write file
-** are handled in the context of that thread.
-** A scheme has been designed to wakeup the kernel-thread as
-** soon as I/O-requests are available in the request-queue; this thread
-** handles the requests one-by-one by calling the proper read- or
-** write-function related to the open read-only file or copy-on-write file.
-** When all pending requests have been handled, the kernel-thread goes
-** back to sleep-state.
-** This approach requires some additional context-switches; however the
-** performance loss during heavy I/O is less than 3%.
