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

Pull ceph updates from Sage Weil:
 "There are some updates and cleanups to the CRUSH placement code, a bug
  fix with incremental maps, several cleanups and fixes from Josh Durgin
  in the RBD block device code, a series of cleanups and bug fixes from
  Alex Elder in the messenger code, and some miscellaneous bounds
  checking and gfp cleanups/fixes."

Fix up trivial conflicts in net/ceph/{messenger.c,osdmap.c} due to the
networking people preferring "unsigned int" over just "unsigned".
