Merge branch 'for_linus' of git://git.kernel.org/pub/scm/linux/kernel/git/jack/linux-fs
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
