| H A D | blk-mq-sched.c | 900e0807 Wed Nov 03 06:47:09 CDT 2021 Jens Axboe <axboe@kernel.dk> block: move queue enter logic into blk_mq_submit_bio()
Retain the old logic for the fops based submit, but for our internal
blk_mq_submit_bio(), move the queue entering logic into the core
function itself.
We need to be a bit careful if going into the scheduler, as a scheduler
or queue mappings can arbitrarily change before we have entered the queue.
Have the bio scheduler mapping do that separately, it's a very cheap
operation compared to actually doing merging locking and lookups.
