Subject: [GIT PULL] Btrfs

Hi Linus,

My for-linus-4.12 branch:

git://git.kernel.org/pub/scm/linux/kernel/git/mason/linux-btrfs.git for-linus-4.12

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
__btrfs_map_block() much more maintainable, and conversions from
atomic_t to refcount_t.
