[GIT PULL] Ceph fixes for 3.12-rc2

[Sage Weil]

Hi Linus,

Please pull the following Ceph fixes for

  git://git.kernel.org/pub/scm/linux/kernel/git/sage/ceph-client.git for-linus

These fix several bugs with RBD from 3.11 that didn't get tested in time 
for the merge window: some error handling, a use-after-free, and a 
sequencing issue when unmapping and image races with a notify operation.

There is also a patch fixing a problem with the new ceph + fscache code 
that just went in.

Thanks!
sage
