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 a lot of refactoring and hardening of the libceph and rbd code
here from Ilya that fix various smaller bugs, and a few more important
fixes with clone overlap. The main fix is a critical change to the
request_fn handling to not sleep that was exposed by the recent mutex
changes (which will also go to teh 3.16 stable series).
Yan Zheng has several fixes in here for CephFS fixing ACL handling, time
stamps, and request resends when the MDS restarts.
Finally, there are a few cleanups from Himangi Saraogi based on
Coccinelle.
Thanks!
sage
