* block: remove the BH_Eopnotsupp flagChristoph Hellwig2010-09-101-4/+1
| | | | | | | | | This flag was only set for barrier buffers, which we don't submit anymore. Signed-off-by: Christoph Hellwig <hch@lst.de> Signed-off-by: Tejun Heo <tj@kernel.org> Signed-off-by: Jens Axboe <jaxboe@fusionio.com>
* remove SWRITE* I/O typesChristoph Hellwig2010-08-181-1/+3
| | | | | | | | | | | | | | | | | These flags aren't real I/O types, but tell ll_rw_block to always lock the buffer instead of giving up on a failed trylock. Instead add a new write_dirty_buffer helper that implements this semantic and use it from the existing SWRITE* callers. Note that the ll_rw_block code had a bug where it didn't promote WRITE_SYNC_PLUG properly, which this patch fixes. In the ufs code clean up the helper that used to call ll_rw_block to mirror sync_dirty_buffer, which is the function it implements for compound buffers.

| | | | | | | | | | | | | | It is not necessary to write custom code for convert calendar time to broken-down time. time_to_tm() is more generic to do that.

| * fat: Check s_dirt in fat_sync_fs()OGAWA Hirofumi2009-09-201-3/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | If we didn't check sb->s_dirt, it will update the FSINFO unconditionally. It will reduce the filetime of flash base device. So, this checks sb->s_dirt. sb->s_dirt is racy, however FSINFO is just hint. So even if there is race, and we hit it, it would not become big problem. And this also is as workaround of suspend problem. Signed-off-by: OGAWA Hirofumi <hirofumi@mail.parknet.co.jp>
* | fat: Opencode sync_page_range_nolock()Jan Kara2009-09-141-2/+2
|/ | | | | | | | | | | | fat_cont_expand() is the only user of sync_page_range_nolock(). It's also the only user of generic_osync_inode() which does not have a file open. So opencode needed actions for FAT so that we can convert generic_osync_inode() to a standard syncing path. Update a comment about generic_osync_inode().

* FAT: add 'errors' mount optionDenis Karpov2009-06-041-8/+14
| | | | | | | | | | | | | | On severe errors FAT remounts itself in read-only mode. Allow to specify FAT fs desired behavior through 'errors' mount option: panic, continue or remount read-only. `mount -t [fat|vfat] -o errors=[panic,remount-ro,continue] \ <bdev> <mount point>` This is analog to ext2 fs 'errors' mount option.

* fat: Fix and cleanup timestamp conversionOGAWA Hirofumi2008-11-061-41/+107
| | | | | | | | | | | | | This cleans date_dos2unix()/fat_date_unix2dos() up. New code should be much more readable. And this fixes those old functions. Those doesn't handle 2100 correctly. 2100 isn't leap year, but old one handles it as leap year. Also, with this, centi sec is handled and is fixed.

* fatfs: add UTC timestamp optionJoe Peterson2008-07-251-4/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Provide a new mount option ("tz=UTC") for DOS (vfat/msdos) filesystems, allowing timestamps to be in coordinated universal time (UTC) rather than local time in applications where doing this is advantageous. In particular, portable devices that use fat/vfat (such as digital cameras) can benefit from using UTC in their internal clocks, thus avoiding daylight saving time errors and general time ambiguity issues. The user of the device does not have to worry about changing the time when moving from place or when daylight saving changes. The new mount option, when set, disables the counter-adjustment that Linux currently makes to FAT timestamp info in anticipation of the normal userspace time zone correction. When used in this new mode, all daylight saving time and time zone handling is done in userspace as is normal for many other filesystems (like ext3). The default mode, which remains unchanged, is still appropriate when mounting volumes written in Windows (because of its use of local time). I originally based this patch on one submitted last year by Paul Collins, but I updated it to work with current source and changed variable/option naming. Ogawa Hirofumi (who maintains these filesystems) and I discussed this patch at length on lkml, and he suggested using the option name in the attached version of the patch. Barry Bouwsma pointed out a good addition to the patch as well.

* Linux-2.6.12-rc2Linus Torvalds2005-04-161-0/+225
Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
