Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/sage/ceph-client
Pull Ceph changes from Sage Weil: "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."
