[GIT PULL] Ceph updates for 3.11

[Sage Weil]

Hi Linus,

Please pull the following Ceph updates from

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

There is some follow-on RBD cleanup after the last window's code drop, a 
series from Yan fixing multi-mds behavior in cephfs, and then a sprinkling 
of bug fixes all around.  Some warnings, sleeping while atomic, a null 
dereference, and cleanups.

Thanks!
sage
