Hi Linus,

After merging the  tree, today's linux-next build (x86_64 allmodconfig)
failed like this:

fs/ceph/msgpool.c: In function 'ceph_msgpool_put':
fs/ceph/msgpool.c:173: error: implicit declaration of function 'kref_set'

I cherry-picked the fix (commit f553069e5d7c6f53688ae4470173fcb1be97cbe7
"ceph: update for removal of kref_set") from the ceph tree.  I believe that Sage has sent you a pull request that includes this fix.
