Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/sage/ceph-client
Pull Ceph updates from Sage Weil:
"This has a mix of bug fixes and cleanups.
Alex's patch fixes a rare race in RBD. Ilya's patches fix an ENOENT
check when a second rbd image is mapped and a couple memory leaks.
Zheng fixes several issues with fragmented directories and multiple
MDSs. Josh fixes a spin/sleep issue, and Josh and Guangliang's
patches fix setting and unsetting RBD images read-only.
Naturally there are several other cleanups mixed in for good measure"
