Hi Linus,

Please pull my for-linus branch:

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

This is against 3.11-rc7, but was pulled and tested against your tree as
of yesterday. We do have two small incrementals queued up, but I wanted
to get this bunch out the door before I hop on an airplane.

This is a fairly large batch of fixes, performance improvements, and
cleanups from the usual Btrfs suspects.

We've included Stefan Behren's work to index subvolume UUIDs, which is
targeted at speeding up send/receive with many subvolumes or snapshots
in place. It closes a long standing performance issue that was built
in to the disk format.

Mark Fasheh's offline dedup work is also here. In this case offline
means the FS is mounted and active, but the dedup work is not done
inline during file IO. This is a building block where utilities are
able to ask the FS to dedup a series of extents. The kernel takes
care of verifying the data involved really is the same. Today this
involves reading both extents, but we'll continue to evolve the patches.
