blk-mq-sched: remove unused 'can_block' arg from blk_mq_sched_insert_request
After commit: 923218f6166a ("blk-mq: don't allocate driver tag upfront for flush rq") we no longer use the 'can_block' argument in blk_mq_sched_insert_request(). Kill it. Signed-off-by: Mike Snitzer <snitzer@redhat.com> Added actual commit message as to why it's being removed. Signed-off-by: Jens Axboe <axboe@kernel.dk>
