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] blk_mq_freeze_queue_start(q); ^ 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.
