Subject: [PATCH 01/14] io_uring: clean poll tw PF_EXITING handling
Date: Fri, 15 Apr 2022 22:08:20 +0100 [thread overview]
Message-ID: <f0cc981af82a5b193658f8f44397eeb3bf838b7b.1650056133.git.asml.silence@gmail.com> (raw)
In-Reply-To: <[email protected]>
When we meet PF_EXITING in io_poll_check_events(), don't overcomplicate
the code with io_poll_mark_cancelled() but just return -ECANCELED and
the callers will deal with the rest.
