From: Pavel Begunkov Date: Fri, 27 Jan 2023 17:01:56 +0000 (-0700) Subject: io_uring: use state completion infra for poll reqs X-Git-Url: https://git.kernel.dk/?a=commitdiff_plain;h=refs%2Fheads%2F5.15-stable;p=linux-2.6-block.git io_uring: use state completion infra for poll reqs commit 0ec6dca223195aca2f7df6e432c4205b5f63305b upstream. Use io_req_task_complete() for poll request completions, so it can utilise state completions and save lots of unnecessary locking.
