Pull ext2, ext3 and quota fixes from Jan Kara: "Interesting bits are: - removal of a special i_mutex locking subclass (I_MUTEX_QUOTA) since quota code does not need i_mutex anymore in any unusual way. - backport (from ext4) of a fix of a checkpointing bug (missing cache flush) that could lead to fs corruption on power failure The rest are just random small fixes & cleanups." * 'for_linus' of git://git.kernel.org/pub/scm/linux/kernel/git/jack/linux-fs: ext2: trivial fix to comment for ext2_free_blocks ext2: remove the redundant comment for ext2_export_ops ext3: return 32/64-bit dir name hash according to usage type quota: Get rid of nested I_MUTEX_QUOTA locking subclass quota: Use precomputed value of sb_dqopt in dquot_quota_sync ext2: Remove i_mutex use from ext2_quota_write() reiserfs: Remove i_mutex use from reiserfs_quota_write() ext4: Remove i_mutex use from ext4_quota_write() ext3: Remove i_mutex use from ext3_quota_write() quota: Fix double lock in add_dquot_ref() with CONFIG_QUOTA_DEBUG jbd: Write journal superblock with WRITE_FUA after checkpointing jbd: protect all log tail updates with j_checkpoint_mutex jbd: Split updating of journal superblock and marking journal empty ext2: do not register write_super within VFS ext2: Remove s_dirt handling ext2: write superblock only once on unmount ext3: update documentation with barrier=1 default ext3: remove max_debt in find_group_orlov() jbd: Refine commit writeout logic

ext2: Remove s_dirt handling

2012-04-11T09:12:45+00:00

Places which modify superblock feature / state fields mark the superblock buffer dirty so it is written out by flusher thread. Thus there's no need to set s_dirt there. The only other fields changing in the superblock are the numbers of free blocks, free inodes and s_wtime. There's no real need to write (or even compute) these periodically. Free blocks / inodes counters are recomputed on every mount from group counters anyway and value of s_wtime is only informational and imprecise anyway. So it should be enough to write these opportunistically on mount, remount, umount, and sync_fs times. Signed-off-by: Jan Kara

fs/ext2/balloc.c: delete useless initialization

2011-08-17T09:41:20+00:00

Delete nontrivial initialization that is immediately overwritten by the result of an allocation function. The semantic match that makes this change is as follows: (http://coccinelle.lip6.fr/) // @@ type T; identifier i; expression e; @@ ( T i = \(0\|NULL\|ERR_PTR(...)\); | -T i = e; +T i; ) ... when != i i = \(kzalloc\|kcalloc\|kmalloc\)(...); // Signed-off-by: Julia Lawall Signed-off-by: Jan Kara

ext2: Avoid loading bitmaps for full groups during block allocation

2010-05-21T17:30:37+00:00

There is no point in loading bitmap for groups which are completely full. This causes noticeable performance problems (and memory pressure) on small systems with large full filesystem (http://marc.info/?l=linux-ext4&m=126843108314310&w=2). Port of the same ext3 patch. Signed-off-by: Jan Kara
