Merge branch 'for-linus-4.7' of git://git.kernel.org/pub/scm/linux/kernel/git/mason/linux-btrfs

Pull btrfs cleanups and fixes from Chris Mason:
 "We have another round of fixes and a few cleanups.

  I have a fix for short returns from btrfs_copy_from_user, which
  finally nails down a very hard to find regression we added in v4.6.

  Dave is pushing around gfp parameters, mostly to cleanup internal apis
  and make it a little more consistent.

  The rest are smaller fixes, and one speelling fixup patch"
