[GIT PULL] space cache and mixed block groups

[GIT PULL] space cache and mixed block groups

[Josef Bacik]

Hello,

Here is part 2 of my outstanding patches, they are in 

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

and have just the disk space caching stuff and the mixed block groups patches.
It should apply cleanly onto the bug-fixes branch.  I would have combined them
but I screwed up my tree again somehow.  Below is the shortlog and diffstat,
thanks


Josef Bacik (7):
      Btrfs: create special free space cache inode
      Btrfs: write out free space cache
      Btrfs: load free space cache if it exists
      Btrfs: check cache->caching_ctl before returning if caching has started
      Btrfs: add support for mixed data+metadata block groups
      Btrfs: Add a clear_cache mount option
      Btrfs: let the user know space caching is enabled
