Merge tag 'ext4_for_linus_stable' of git://git.kernel.org/pub/scm/linux/kernel/git/tytso/ext4
Pull ext4 fixes from Ted Ts'o:
"Some miscellaneous ext4 fixes for 4.18; one fix is for a regression
introduced in 4.18-rc4.
Sorry for the late-breaking pull. I was originally going to wait for
the next merge window, but Eric Whitney found a regression introduced
in 4.18-rc4, so I decided to push out the regression plus the other
fixes now. (The other commits have been baking in linux-next since
early July)"
