Subject: [PATCH 06/13] io-wq: simplify worker exiting
Date: Mon, 14 Jun 2021 02:36:17 +0100	[thread overview]
Message-ID: <7521e485677f381036676943e876a0afecc23017.1623634181.git.asml.silence@gmail.com> (raw)
In-Reply-To: <[email protected]>

io_worker_handle_work() already takes care of the empty list case and
releases spinlock, so get rid of ugly conditional unlocking and
unconditionally call handle_work()
