[GIT PULL] Ceph changes for 4.3-rc1

[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 are a few fixes for snapshot behavior with CephFS and support for 
the new keepalive protocol from Zheng, a libceph fix that affects both RBD 
and CephFS, a few bug fixes and cleanups for RBD from Ilya, and several 
small fixes and cleanups from Jianpeng and others.

Thanks!
sage
