[GIT PULL] Ceph updates for 4.6-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 is quite a bit here, including some overdue refactoring and cleanup 
on the mon_client and osd_client code from Ilya, scattered writeback 
support for CephFS and a pile of bug fixes from Zheng, and a few random 
cleanups and fixes from others.

This series is based on a recent merge of Al's tree to avoid conflicts 
with his splice_dentry changes.

Thanks!
sage
