[GIT PULL] Ceph updates for 4.1-rc1

[Sage Weil]

Hi Linux,

Please pull the following Ceph updates from

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

This time around we have a collection of CephFS fixes from Zheng around 
MDS failure handling and snapshots, support for a new CRUSH straw2 
algorithm (to sync up with userspace) and several RBD cleanups and fixes 
from Ilya, an error path leak fix from Taesoo, and then an assorted 
collection of cleanups from others.

Thanks!
sage
