[GIT PULL] Btrfs updates for 3.1

[Josef Bacik <josef@redhat.com>]

Hey Chris,

Since I'm going on vacation next week I wanted to get everything ready for you
in case you get bored with fsck and want to put together a 3.1 tree :).  If you
can pull

git://git.kernel.org/pub/scm/linux/kernel/git/josef/btrfs-work.git for-chris

It is based on your for-linus branch.  Here is the shortlog and diffstat

Josef Bacik (7):
      Btrfs: try to only do one btrfs_search_slot in do_setxattr
      Btrfs: do transaction space reservation before joining the transaction
      Btrfs: serialize flushers in reserve_metadata_bytes
      Btrfs: use the normal checksumming infrastructure for free space cache
      Btrfs: fix how we merge extent states and deal with cached states
      Btrfs: use a worker thread to do caching
      Btrfs: don't panic if we get an error while balancing
