Subject: [PATCH 07/14] io_uring: simplify io_alloc_req()
Date: Tue, 19 Jan 2021 13:32:40 +0000 [thread overview]
Message-ID: <f1c14fb26ef6651872a168b3f74d9eedbc577d01.1611062505.git.asml.silence@gmail.com> (raw)
In-Reply-To: <[email protected]>
Get rid of a label in io_alloc_req(), it's cleaner to do return
directly.
