Subject: [PATCH v2 23/24] io_uring: comment why inline complete calls io_clean_op()
Date: Fri, 24 Sep 2021 22:00:03 +0100	[thread overview]
Message-ID: <21806f862151e223fdf439e5e8ed7178a8d66979.1632516769.git.asml.silence@gmail.com> (raw)
In-Reply-To: <[email protected]>

io_req_complete_state() calls io_clean_op() and it may be not entirely
obvious, leave a comment.
