Hi Sage,
Today's linux-next merge of the ceph tree got a conflict in
fs/ceph/super.c between commit 5dfc589a8467470226feccdc50f1b32713318e7b
("ceph: unregister bdi before kill_anon_super releases device name") from
Linus' tree and commits 9f2a2a1faa0fd990d4930605583a67d7dff28bff ("ceph:
use ceph_sb_to_client instead of ceph_client") and
c72b09ba224e6f2c00bcf810a0a62059fcf405f7 ("ceph: name bdi ceph-%d instead
of major:minor") from the ceph tree.
I fixed it up (see below) and can carry the fix for a while.
