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.
Thank you for your response. Commit 1e9364283764 just fix some comments, real funtional modification should before that. And I do agree that commit 7b36a7189fc3 is the right one. By the way, do you agree the way I fix the CVE? I can send a V2 patch if you do. Thanks! Yu Kuai
