Subject: [PATCH RFC v2 1/5] blk-mq: Remove some unused function arguments
Date: Tue, 19 Nov 2019 22:27:34 +0800	[thread overview]
Message-ID: <1574173658-76818-2-git-send-email-john.garry@huawei.com> (raw)
In-Reply-To: <1574173658-76818-1-git-send-email-john.garry@huawei.com>

The struct blk_mq_hw_ctx * argument in blk_mq_put_tag(),
blk_mq_poll_nsecs(), and blk_mq_poll_hybrid_sleep() is unused, so remove
it.
