[GIT PULL] Ceph changes for 2.6.38-rc1

[Sage Weil]

Hi Linus,

Please pull the following Ceph updates for 2.6.38 from

  git://git.kernel.org/pub/scm/linux/kernel/git/sage/ceph-client.git for-linus

There are a few error path fixes (libceph and rbd), some ceph code 
cleanup, improved support for (server-side) directory hashing, and some 
patches from Tejun switching to the new workqueue API and removing 
unnecessary hijinks that the workqueues can handle themselves.

Thanks!
sage
