The really interesting commit is
    btrfs: don't spin in shrink_delalloc if there is nothing to free
which fixes hogs on ENOSPC for me.


The rest of patches are cleanup.

Change since v2:
- Rebased against 2.6.39

Change since v1:
- Added Josef's Reviewed-by
- Fixed my MTA and patch numbering

Thanks!

P.S.:
It's also interesting to note, that 'shrink_delalloc' tries
to mess with 'bytes_reserved' (which are metadata reservation
right?)

The more I look at 'bytes_reserved' management paths the more I
think 'shrink_delalloc' should not touch them.
