Subject: [PATCH V3 2/2] block: remove unnecessary argument from blk_execute_rq
Date:   Mon, 25 Jan 2021 05:49:58 +0100
Message-Id: <1611550198-17142-3-git-send-email-guoqing.jiang@cloud.ionos.com>
In-Reply-To: <1611550198-17142-1-git-send-email-guoqing.jiang@cloud.ionos.com>
References: <1611550198-17142-1-git-send-email-guoqing.jiang@cloud.ionos.com>
Precedence: bulk

We can remove 'q' from blk_execute_rq as well after the previous change
in blk_execute_rq_nowait.

And more importantly it never really was needed to start with given
that we can trivial derive it from struct request.
