Subject: [PATCH v16 10/26] blk-mq: Clean up blk_mq_requeue_work()
Date: Mon, 18 Nov 2024 16:27:59 -0800 [thread overview]
Message-ID: <20241119002815.600608-11-bvanassche@acm.org> (raw)
In-Reply-To: <20241119002815.600608-1-bvanassche@acm.org>
Move a statement that occurs in both branches of an if-statement in front
