[GIT PULL] XFS 2nd update for 2.6.39-rc1

[Alex Elder]

Linus, please pull the following XFS changes for 2.6.39-rc3.

They fall into these categories:
- switching XFS daemons over to use workqueues, taking advantage of
  the recent global workqueue improvements
- improving how the new per-process device plugging is used in XFS
- alleviating some OOM issues reported by Chris Mason
- reducing memory use in some log code (where it could needlessly
  allocate much more than required)
- checking for and reporting bad extents when they are found during
  free (instead of using ASSERT())
- eliminating warnings (some of which have begun to show up with
  newer gcc)

Thank you.
