Subject: [PATCH for-next v2 20/25] io_uring: use state completion infra for poll reqs
Date: Tue, 14 Jun 2022 15:37:10 +0100 [thread overview]
Message-ID: <f020410e5970a68d2471081eeb07ade292e9013d.1655213915.git.asml.silence@gmail.com> (raw)
In-Reply-To: <[email protected]>
Use io_req_task_complete() for poll request completions, so it can
utilise state completions and save lots of unnecessary locking.
