Merge branch 'for-linus-4.12' of git://git.kernel.org/pub/scm/linux/kernel/git/mason/linux-btrfs

Pull btrfs updates from Chris Mason:
 "This has fixes and cleanups Dave Sterba collected for the merge
  window.

  The biggest functional fixes are between btrfs raid5/6 and scrub, and
  raid5/6 and device replacement. Some of our pending qgroup fixes are
  included as well while I bash on the rest in testing.

  We also have the usual set of cleanups, including one that makes
  __btrfs_map_block() much more maintainable, and conversions from
  atomic_t to refcount_t"
