Subject: [PATCH 11/13] nvme-loop: store the generic nvme_ctrl in set->driver_data
Date: Tue, 20 Sep 2022 19:16:09 +0200 [thread overview]
Message-ID: <20220920171611.1289361-12-hch@lst.de> (raw)
In-Reply-To: <20220920171611.1289361-1-hch@lst.de>
Point the private data to the generic controller structure in preparation
of using the common tagset init/exit code.
