[GIT PULL] Ceph updates for 3.18-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 the long-awaited discard support for RBD (Guangliang Zhao, Josh
Durgin), a pile of RBD bug fixes that didn't belong in late -rc's (Ilya
Dryomov, Li RongQing), a pile of fs/ceph bug fixes and performance and
debugging improvements (Yan, Zheng, John Spray), and a smattering of
cleanups (Chao Yu, Fabian Frederick, Joe Perches).

Thanks!
sage
