[GIT PULL] Ceph updates for 3.5

[Sage Weil]

Hi Linus,

Please pull the following Ceph updates for rc1 from

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

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.

There are a couple of simple merge conflict resolutions that Stephen is 
carrying in linux-next in net/ceph/messenger.c and net/ceph/osdmap.c.

Thanks!
sage
