Merge branch 'for-linus' of git://git./linux/kernel/git/sage/ceph-client

Pull two ceph fixes from Sage Weil:
 "The first patch fixes a problem when we have a page count of 0 for
  sendpage which is triggered by zfs.  The second fixes a bug in CRUSH
  that was resolved in the userland code a while back but fell through
  the cracks on the kernel side"

* 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/sage/ceph-client:
  crush: decode and initialize chooseleaf_vary_r
  libceph: fix corruption when using page_count 0 page in rbd
