Subject: [GIT PULL] Btrfs updates for 2.6.29-rc

Hello everyone,

The master branch
git://git.kernel.org/pub/scm/linux/kernel/git/mason/btrfs-unstable.git

Has the following fixes and updates for 2.6.29-rc.  There is also a
branch named experimental that is very very experimental.

I think I pushed things out correctly so that master and experimental
didn't mix, but we've long established my ability to mess that part up.

These are cleanups and fixes that came out of testing and review.  The
lockdep fix is actually the biggest in terms of code, but that is under
CONFIG_DEBUG_LOCK_ALLOC.

SSD mode is changed to work better on ssds that do random writes poorly,
and btrfs_sync_fs is changed to skip the cleaning of old snapshots.
That still happens in the background, and it was making sync look slower
than it really was.

mount -o remount finally looks at the new options sent, so you can send
important things like mount -o compress,ssd for remounting now.

-chris
