Subject: [PATCH 03/16] blk-mq: provide dummy blk_mq_map_queue_type() helper
Date:   Tue, 30 Oct 2018 12:32:39 -0600
Message-Id: <20181030183252.17857-4-axboe@kernel.dk>
In-Reply-To: <20181030183252.17857-1-axboe@kernel.dk>
References: <20181030183252.17857-1-axboe@kernel.dk>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

Doesn't do anything right now, but it's needed as a prep patch
to get the interfaces right.

While in there, correct the blk_mq_map_queue() CPU type to an unsigned
int.
