Merge tag 'ext4_for_linus_stable' of git://git.kernel.org/pub/scm/linux/kernel/git/tytso/ext4
Pull ext4 bugfixes from Ted Ts'o:
"More bug fixes for ext4 -- most importantly, a fix for a bug
introduced in 3.15 that can end up triggering a file system corruption
error after a journal replay.
It shouldn't lead to any actual data corruption, but it is scary and
can force file systems to be remounted read-only, etc"
