Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/sage/ceph-client

Pull Ceph fix from Sage Weil:
"This sets the stable pages flag on the RBD block device when we have
CRCs enabled. (This is necessary since the default assumption for
block devices changed in 3.9)"

* 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/sage/ceph-client:
rbd: require stable pages if message data CRCs are enabled
