Merge tag 'ext4_for_linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tytso/ext4
Pull ext4 updates from Ted Ts'o:
"This merge window, we've added some performance improvements in how we
handle inode locking in the read/write paths, and improving the
performance of Direct I/O overwrites.
We also now record the error code which caused the first and most
recent ext4_error() report in the superblock, to make it easier to
root cause problems in production systems.
There are also many of the usual cleanups and miscellaneous bug fixes"
