Merge tag 'for-4.16-rc5-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/kdave/linux

Pull btrfs fixes from David Sterba:
 "There's an important revert in this pull request that needs to go to
  stable as it causes a corruption on big endian machines.

  The other fix is for FIEMAP incorrectly reporting shared extents
  before a sync and one fix for a crash in raid56.

  So far we got only one report about the BE corruption, the stable
  kernels were out for like a week, so hopefully the scope of the damage
  is low"
