I think the second commit reference is wrong. Did you perhaps want to
refer to commit 7b36a7189fc3 ("block: don't call ioc_exit_icq() with the
queue lock held for blk-mq")? That is the commit that removed the
locking from blk_release_queue() and that makes it safe to revert commit
dc9edc44de6c.
Thanks,
Bart.
