* [PATCH] Streamline generic_file_* interfaces and filemap cleanupsBadari Pulavarty2006-10-0127-165/+105
| | | | | | | | | | | | | | | | | | | | | | This patch cleans up generic_file_*_read/write() interfaces. Christoph Hellwig gave me the idea for this clean ups. In a nutshell, all filesystems should set .aio_read/.aio_write methods and use do_sync_read/ do_sync_write() as their .read/.write methods. This allows us to cleanup all variants of generic_file_* routines. Final available interfaces: generic_file_aio_read() - read handler generic_file_aio_write() - write handler generic_file_aio_write_nolock() - no lock write handler __generic_file_aio_write_nolock() - internal worker routine Signed-off-by: Badari Pulavarty <pbadari@us.ibm.com> Signed-off-by: Christoph Hellwig <hch@lst.de> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>

* [PATCH] reiserfs: eliminate minimum window size for bitmap searchingJeff Mahoney2006-10-011-22/+1
| | | | | | | | | | | | | | | | | | | | When a file system becomes fragmented (using MythTV, for example), the bigalloc window searching ends up causing huge performance problems. In a file system presented by a user experiencing this bug, the file system was 90% free, but no 32-block free windows existed on the entire file system. This causes the allocator to scan the entire file system for each 128k write before backing down to searching for individual blocks. In the end, finding a contiguous window for all the blocks in a write is an advantageous special case, but one that can be found naturally when such a window exists anyway. This patch removes the bigalloc window searching, and has been proven to fix the test case described above.

* [PATCH] reiserfs: use generic_file_open for open() checksJeff Mahoney2006-10-011-0/+1
| | | | | | | | | | | | | | | | | The other common disk-based file systems (I checked ext[23], xfs, jfs) check to ensure that opens of files > 2 GB fail unless O_LARGEFILE is specified. They check via generic_file_open or their own open routine. ReiserFS doesn't have an f_op->open defined, and as such, it's possible to open files > 2 GB without O_LARGEFILE. This patch adds the f_op->open member to conform with the expected behavior.

* [PATCH] reiserfs: on-demand bitmap loadingJeff Mahoney2006-10-014-91/+70
| | | | | | | | | | | | | | | | | | | | | | | | | | This is the patch the three previous ones have been leading up to. It changes the behavior of ReiserFS from loading and caching all the bitmaps as special, to treating the bitmaps like any other bit of metadata and just letting the system-wide caches figure out what to hang on to. Buffer heads are allocated on the fly, so there is no need to retain pointers to all of them. The caching of the metadata occurs when the data is read and updated, and is considered invalid and uncached until then. I needed to remove the vs-4040 check for performing a duplicate operation on a particular bit. The reason is that while the other sites for working with bitmaps are allowed to schedule, is_reusable() is called from do_balance(), which will panic if a schedule occurs in certain places. The benefit of on-demand bitmaps clearly outweighs a sanity check that depends on a compile-time option that is discouraged.

* [PATCH] reiserfs: reorganize bitmap loading functionsJeff Mahoney2006-10-014-113/+94
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch moves the bitmap loading code from super.c to bitmap.c The code is also restructured somewhat. The only difference between new format bitmaps and old format bitmaps is where they are. That's a two liner before loading the block to use the correct one. There's no need for an entirely separate code path. The load path is generally the same, with the pattern being to throw out a bunch of requests and then wait for them, then cache the metadata from the contents. Again, like the previous patches, the purpose is to set up for later ones. Update: There was a bug in the previously posted version of this that resulted in corruption. The problem was that bitmap 0 on new format file systems must be treated specially, and wasn't. A stupid bug with an easy fix. This is hopefully the last fix for the disaster that is the reiserfs bitmap patch set. If a bitmap block was full, first_zero_hint would end up at zero since it would never be changed from it's zeroed out value. This just sets it beyond the end of the bitmap block. If any bits are freed, it will be reset to a valid bit. When info->free_count = 0, then we already know it's full.

* [PATCH] reiserfs: clean up bitmap block buffer head referencesJeff Mahoney2006-10-012-49/+71
| | | | | | | | | | | | | | | | | | Similar to the SB_JOURNAL cleanup that was accepted a while ago, this patch uses a temporary variable for buffer head references from the bitmap info array. This makes the code much more readable in some areas. It also uses proper reference counting, doing a get_bh() after using the pointer from the array and brelse()'ing it later. This may seem silly, but a later patch will replace the simple temporary variables with an actual read, so the reference freeing will be used then.

* [PATCH] reiserfs: fix is_reusable bitmap check to not traverse the bitmap ↵Jeff Mahoney2006-10-013-15/+28
| | | | | | | | | | | | | | | | | | | | info array There is a check in is_reusable to determine if a particular block is a bitmap block. It verifies this by going through the array of bitmap block buffer heads and comparing the block number to each one. Bitmap blocks are at defined locations on the disk in both old and current formats. Simply checking against the known good values is enough. This is a trivial optimization for a non-production codepath, but this is the first in a series of patches that will ultimately remove the buffer heads from that array.

* [PATCH] kill wall_jiffiesAtsushi Nemoto2006-10-0126-190/+35
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | With 2.6.18-rc4-mm2, now wall_jiffies will always be the same as jiffies. So we can kill wall_jiffies completely. This is just a cleanup and logically should not change any real behavior except for one thing: RTC updating code in (old) ppc and xtensa use a condition "jiffies - wall_jiffies == 1". This condition is never met so I suppose it is just a bug. I just remove that condition only instead of kill the whole "if" block.

* [PATCH] ntp: convert to the NTP4 reference modelRoman Zippel2006-10-012-38/+24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | This converts the kernel ntp model into a model which matches the nanokernel reference implementations. The previous patches already increased the resolution and precision of the computations, so that this conversion becomes quite simple. <linux@horizon.com> explains: The original NTP kernel interface was defined in units of microseconds. That's what Linux implements. As computers have gotten faster and can now split microseconds easily, a new kernel interface using nanosecond units was defined ("the nanokernel", confusing as that name is to OS hackers), and there's an STA_NANO bit in the adjtimex() status field to tell the application which units it's using. The current ntpd supports both, but Linux loses some possible timing resolution because of quantization effects, and the ntpd hackers would really like to be able to drop the backwards compatibility code. Ulrich Windl has been maintaining a patch set to do the conversion for years, but it's hard to keep in sync.

* [PATCH] ip2: use newer pci_get functionsAlan Cox2006-10-011-3/+7
| | | | | | | | | | | | This is one of a series of patches I plan to gradually trickle into the tree which eliminates almost all remaining use of pci_find_* and lets me build a pci_find_* free kernel for all but some obscure ISDN and SCSI drivers. This is important as all pci_find_* users are not hotplug safe - even if they are not the device being plugged.

* [PATCH] update legacy io handling for pmacOlaf Hering2006-10-015-9/+26
| | | | | | | | | | | | | | | | | | | | | | | | | | ppc can boot one single binary on prep, chrp and pmac boards. ppc64 can boot one single binary on pseries and G5 boards. pmac has no legacy io, probing for PC style legacy hardware (or accessing the legacy io area regulary) may lead to a hard crash: * add check for parport_pc, exit on pmac. 32bit chrp has no ->check_legacy_ioport, the probe is always called. 64bit chrp has check_legacy_ioport, check for a "parallel" node * add check for isapnp, only PReP boards may have real ISA slots. 32bit PReP will have no ->check_legacy_ioport, the probe is always called. * update code in i8042_platform_init. Run ->check_legacy_ioport first, always call request_region. No functional change. Remove whitespace before i8042_reset init.
