Subject: [PATCH v2 2/3] io_uring: simplify __io_uring_add_tctx_node
Date: Mon, 26 Sep 2022 10:09:26 -0700 [thread overview]
Message-ID: <[email protected]> (raw)
In-Reply-To: <[email protected]>
Remove submitter parameter from __io_uring_add_tctx_node.
It was only called from one place, and we can do that logic in that one
place.
Signed-off-by: Dylan Yudaken <[email protected]>
