Hi all,

After merging the tip tree, today's linux-next build (x86_64 allmodconfig)
failed like this:

drivers/nvdimm/pmem.c: In function 'pmem_freeze_queue':
drivers/nvdimm/pmem.c:237:2: error: implicit declaration of function 'blk_mq_freeze_queue_start' [-Werror=implicit-function-declaration]

Caused by commit

71389703839e ("mm, zone_device: Replace {get, put}_zone_device_page() with a single reference to fix pmem crash")

interacting with commit

1671d522cdd9 ("block: rename blk_mq_freeze_queue_start()")

from Linus' tree.

I have applied the merge fix patch below.
