Merge tag 'ext4_for_linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tytso/ext4

Pull ext4 updates from Ted Ts'o:
 "For this cycle we add support for the shutdown ioctl, which is
  primarily used for testing, but which can be useful on production
  systems when a scratch volume is being destroyed and the data on it
  doesn't need to be saved.

  This found (and we fixed) a number of bugs with ext4's recovery to
  corrupted file system --- the bugs increased the amount of data that
  could be potentially lost, and in the case of the inline data feature,
  could cause the kernel to BUG.

  Also included are a number of other bug fixes, including in ext4's
  fscrypt, DAX, inline data support"
