Hi Sage,

After merging the ceph tree, today's linux-next build (x86_64
allmodconfig) produced this warning:

In file included from fs/ceph/super.h:4:0,
from fs/ceph/cache.c:26:
include/linux/ceph/ceph_debug.h:4:0: warning: "pr_fmt" redefined [enabled by default]
#define pr_fmt(fmt) KBUILD_MODNAME ": " fmt
^

from fs/ceph/cache.c:24:
include/linux/printk.h:206:0: note: this is the location of the previous definition
#define pr_fmt(fmt) fmt
^

Probably introduced by commit cb0963fcf836 ("ceph: use fscache as a local
presisent cache").

pr_fmt needs to be defined before printk.h gets included.
