Subject: linux-next: manual merge of the ceph tree with Linus' tree

Hi Sage,

Today's linux-next merge of the ceph tree got a conflict in
fs/ceph/messenger.c between commit
45c6ceb547ad2d98215351974a4686bf8cb13e14 ("ceph: zero unused message
header, footer fields") from Linus' tree and commit
c46c4a323cad3fb2678a6b9ffd200b7640b0dc61 ("ceph: simplify ceph_msg_new")
from the ceph tree.

I fixed it up (I think - see below) and can carry the fix for a while.
