Subject: [PATCH 09/11] io_uring: inline __io_cq_unlock
Date: Fri, 23 Jun 2023 12:23:29 +0100 [thread overview]
Message-ID: <d875c4cfb69f38ccecb58a57111446c77a614caa.1687518903.git.asml.silence@gmail.com> (raw)
In-Reply-To: <[email protected]>
__io_cq_unlock is not very helpful, and users should be calling flush
variants anyway. Open code the function.
