Hi Linus,

Please pull my for-linus branch:

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

These are fixes and cleanups, including a first stab at fixing some
deadlocks we've hit since v3.15 in the btrfs workqueues. We have one
more fix cooking on that side not included here.

Mark Fasheh has fixed more problems with quotas during snapshot
deletion, it is working much better now.
