Subject: [PATCH 2/6] io_uring: deduplicate __io_complete_rw()
Date: Thu, 30 Jul 2020 18:43:46 +0300 [thread overview]
Message-ID: <571f3037d6b7fa885dc075e56224cafcdfd68eaf.1596123376.git.asml.silence@gmail.com> (raw)
In-Reply-To: <cover.1596123376.git.asml.silence@gmail.com>
Call __io_complete_rw() in io_iopoll_queue() instead of hand coding it.
