Subject: [PATCH 02/10] io_uring: remove 'sqe' parameter to the OP helpers that take it
Date: Fri, 13 Dec 2019 11:36:24 -0700
Message-ID: <20191213183632.19441-3-axboe@kernel.dk> (raw)
In-Reply-To: <20191213183632.19441-1-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.
