Hi Ming,
[auto build test ERROR on block/for-next]
[also build test ERROR on v4.12-rc2 next-20170525]

base: https://git.kernel.org/pub/scm/linux/kernel/git/axboe/linux-block.git for-next
config: x86_64-randconfig-x019-201721 (attached as .config)
compiler: gcc-6 (Debian 6.2.0-3) 6.2.0 20160901
reproduce:
# save the attached .config to linux build tree
make ARCH=x86_64
Note: the linux-review/Ming-Lei/blk-mq-introduce-blk_mq_unquiesce_queue/20170526-140138 HEAD 470e70e5203ed8f76bb7c1a86db58023098bfc21 builds fine.
It only hurts bisectibility.
All errors (new ones prefixed by >>):
drivers/scsi/scsi_lib.c: In function 'scsi_internal_device_unblock':
>> drivers/scsi/scsi_lib.c:3033:7: error: implicit declaration of function 'blk_queue_quiesced' [-Werror=implicit-function-declaration]
if (blk_queue_quiesced(q))
