Commit a1ce35fa4985 ("block: remove dead elevator code") removed code
that was using the request_queue argument. This got simplified by
calling blk_mq_sched_insert_request which already gets the request_queue
from the request being inserted in the scheduler queue for execution.

Commit a1ce35fa4985 ("block: remove dead elevator code") removed code
that was using the request_queue argument. This got simplified by
calling blk_mq_sched_insert_request which already gets the request_queue
from the request being inserted in the scheduler queue for execution.

The only user of the request_queue argument was removed in commit
552cef2b8b03 ("block: Remove request_queue argument from
blk_execute_rq_nowait"), so now we can safely removed the same argument
from blk_execute_rq and all places that calls this function.

The only user of the request_queue argument was removed in commit
552cef2b8b03 ("block: Remove request_queue argument from
blk_execute_rq_nowait"), so now we can safely removed the same argument
from blk_execute_rq and all places that calls this function.

Don't ever send something out that hasn't even been compiled. I already
detest doing kernel-wide cleanup changes like this, but when I do, I
need absolute confidence in it actually being tested. The fact that it
hasn't even been compiled is a big black mark on the submitter.

My bad. I compiled the code locally and tested in VM, but later on I removed
the semicolon by mistake while reviewing the changes once more and the code
was commited without the semicolon. I'm improving my setup (scripts
and whatnot) to avoid this happening again in the future.
