Pull btrfs updates from Chris Mason:
 "This has a series of fixes and cleanups that Dave Sterba has been
  collecting.

  There is a pretty big variety here, cleaning up internal APIs and
  fixing corner cases"

* 'for-linus-4.11' of git://git.kernel.org/pub/scm/linux/kernel/git/mason/linux-btrfs: (124 commits)
