Subject: [PATCH 05/13] io_uring: remove 'sqe' parameter to the OP helpers that take it
Date: Wed, 18 Dec 2019 10:18:27 -0700 [thread overview]
Message-ID: <20191218171835.13315-6-axboe@kernel.dk> (raw)
In-Reply-To: <20191218171835.13315-1-axboe@kernel.dk>
We pass in req->sqe for all of them, no need to pass it in as the
request is always passed in. This is a necessary prep patch to be
able to cleanup/fix the request prep path.
