Subject: [PATCH 4/4] io_uring: kill NULL checks for submit state
Date: Sun, 21 Jun 2020 13:09:53 +0300 [thread overview]
Message-ID: <4b127f2fd5c4f5587a8c1d497c055cf39ab31cd3.1592733956.git.asml.silence@gmail.com> (raw)
In-Reply-To: <[email protected]>
After recent changes, io_submit_sqes() always passes valid submit state,
so kill leftovers checking it for NULL.
