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."
