Revision 3cfb6772d4cf3875d199f5a5a547cadaef7c1382 authored by Linus Torvalds on 29 July 2018, 20:13:45 UTC, committed by Linus Torvalds on 29 July 2018, 20:13:45 UTC 
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)"

* tag 'ext4_for_linus_stable' of git://git.kernel.org/pub/scm/linux/kernel/git/tytso/ext4:
