Subject: Re: [PATCH] blk-mq: put the reference of the io scheduler module after switching back

Sorry for the disturbance.
This patch is just wrong. elevator_switch_mq does not increase the reference
count of the io scheduler module to which we are switching. Hence, we do not
need to put the reference back manually.
Sincerely
Jinlong Chen
