[GIT PULL] Ceph fixes for -rc4

[Sage Weil]

Hi Linus,

Please pull the following Ceph fixes from

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

There are a couple of fixes from Yan for bad pointer dereferences in the 
messenger code and when fiddling with page->private after page migration, 
a fix from Alex for a use-after-free in the osd client code, and a couple 
fixes for the message refcounting and shutdown ordering.

Thanks!
sage
