Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/sage/ceph-client
Pull ceph fixes from Sage Weil:
"Jim's fix closes a narrow race introduced with the msgr changes. One
fix resolves problems with debugfs initialization that Yan found when
multiple client instances are created (e.g., two clusters mounted, or
rbd + cephfs), another one fixes problems with mounting a nonexistent
server subdirectory, and the last one fixes a divide by zero error
from unsanitized ioctl input that Dan Carpenter found."
* 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/sage/ceph-client:
ceph: avoid divide by zero in __validate_layout()
libceph: avoid truncation due to racing banners
ceph: tolerate (and warn on) extraneous dentry from mds
libceph: delay debugfs initialization until we learn global_id
