Subject: linux-next: build failure after merge of the device-mapper tree

Hi all,

After merging the device-mapper tree, today's linux-next build (powerpc
ppc64_defconfig) failed like this:

ERROR: ".dm_bufio_get_device_size" [drivers/md/dm-snapshot.ko] undefined!
ERROR: ".dm_bufio_release" [drivers/md/dm-snapshot.ko] undefined!
ERROR: ".dm_bufio_client_destroy" [drivers/md/dm-snapshot.ko] undefined!
ERROR: ".dm_bufio_prefetch" [drivers/md/dm-snapshot.ko] undefined!
ERROR: ".dm_bufio_set_minimum_buffers" [drivers/md/dm-snapshot.ko] undefined!
ERROR: ".dm_bufio_forget" [drivers/md/dm-snapshot.ko] undefined!
ERROR: ".dm_bufio_client_create" [drivers/md/dm-snapshot.ko] undefined!
ERROR: ".dm_bufio_read" [drivers/md/dm-snapshot.ko] undefined!

Presumably caused by commit b41bf7440bcf ("dm snapshot: use dm-bufio").

I have used the device-mapper tree from next-20140114 for today.
