Subject: [GIT PULL] Btrfs updates for 2.6.32-rc

Hello everyone,

The master branch of the btrfs-unstable repo has an assortment of fixes
and speedups.

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

These are mostly minor fixes, but there is an important fix for using
btrfs and ceph together.  Josef has a block group caching performance
patch that reduces his boot time dramatically, which is the biggest
change in the bunch.

We also now handle enospc with mount -o compress, before this was
actually more likely to fail than uncompressed mounts because mount -o
compress expected to be able to find multi-block contiguous extents on
disk.

I know Linus likes to look for obvious rebases, and I did rebase this
morning before pushing out to drop a small mount option patch that we
don't strictly need for .32.
