Subject: [PATCH 05/15] io_uring/kbuf: use io_ring_submit_unlock() helper
Date: Fri, 11 Sep 2026 09:40:55 -0600 [thread overview]
Message-ID: <20260911154148.644489-6-axboe@kernel.dk> (raw)
In-Reply-To: <20260911154148.644489-1-axboe@kernel.dk>
io_buffers_select() open-codes how it unlocks the ring based on the
issue_flags, use the generic helper instead.
