Subject: [GIT PULL] Ceph changes for 3.6
Hi Linus,
Please pull the following Ceph changes for 3.6 from
git://git.kernel.org/pub/scm/linux/kernel/git/sage/ceph-client.git for-linus
There are several trivial conflicts to resolve; sorry! Stephen is
carrying fixes for them in linux-next as well.
Lots of stuff this time around:
* lots of cleanup and refactoring in the libceph messenger code, and many
hard to hit races and bugs closed as a result.
* lots of cleanup and refactoring in the rbd code from Alex Elder, mostly in
preparation for the layering functionality that will be coming in 3.7.
* some misc rbd cleanups from Josh Durgin that are finally going upstream
* support for CRUSH tunables (used by newer clusters to improve the data
placement)
* some cleanup in our use of d_parent that Al brought up a while back
* a random collection of fixes across the tree
There is another patch coming that fixes up our ->atomic_open() behavior,
but I'm going to hammer on it a bit more before sending it.
Thanks!
sage
