Subject: [PATCH for-next 1/9] io_uring: kill io_poll_issue's PF_EXITING check
Date: Wed, 30 Nov 2022 15:21:51 +0000 [thread overview]
Message-ID: <2e9dc998dc07507c759a0c9cb5d2fbea0710d58c.1669821213.git.asml.silence@gmail.com> (raw)
In-Reply-To: <[email protected]>
We don't need to worry about checking PF_EXITING in io_poll_issue().
task works using the function should take care of it and never try to
resubmit / retry if the task is dying.
