Merge tag 'ext4_for_linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tytso/ext4
Pull ext4 updates from Ted Ts'o:
"All cleanups and bug fixes; most notably, fix some problems discovered
in ext4's NFS support, and fix an ioctl (EXT4_IOC_GROUP_ADD) used by
old versions of e2fsprogs which we accidentally broke a while back.
Also fixed some error paths in ext4's quota and inline data support.
Finally, improve tail latency in jbd2's commit code"
