[GIT PULL] Ceph fixes for 3.18

[Sage Weil]

Hi Linus,

Please pull the following fixes for RBD from

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

There is a GFP flag fix from Mike Christie, an error code fix from Jan, 
and fixes for two unnecessary allocations (kmalloc and workqueue) from 
Ilya. All are well tested.

Ilya has one other fix on the way but it didn't get tested in time.

Thanks!
sage
