Subject: [PATCH 1/1] virtio_blk: replace 0 by HCTX_TYPE_DEFAULT to index blk_mq_tag_set->map
Date:   Tue, 12 Mar 2019 09:31:56 +0800
Message-Id: <1552354316-20204-1-git-send-email-dongli.zhang@oracle.com>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

Use HCTX_TYPE_DEFAULT instead of 0 to avoid hardcoding.
