Hi Greg,

After merging the driver-core 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'

Caused by commit 10c5d9fdc9ba89606b34f01cbe6ea287abba7395 ("kref: remove
kref_set") from the driver-core tree interacting with commit
c2e552e76e2c6907ca50cd9a4b747a2e2e8c615e ("ceph: use kref for ceph_msg")
from the ceph tree.

I applied the following patch for today (which may not be correct):

[Sage, if this patch is correct, it should be applied to the ceph tree.]
