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:
 "These are regression and bug fixes for ext4.

  We had a number of new features in ext4 during this merge window
  (ZERO_RANGE and COLLAPSE_RANGE fallocate modes, renameat, etc.) so
  there were many more regression and bug fixes this time around.  It
  didn't help that xfstests hadn't been fully updated to fully stress
  test COLLAPSE_RANGE until after -rc1"
