Subject: [PATCH 09/13] nvme-fc: use the tagset alloc/free helpers
Date: Tue, 20 Sep 2022 19:16:07 +0200	[thread overview]
Message-ID: <20220920171611.1289361-10-hch@lst.de> (raw)
In-Reply-To: <20220920171611.1289361-1-hch@lst.de>

Use the common helpers to allocate and free the tagsets.  To make this
work the generic nvme_ctrl now needs to be stored in the hctx private
data instead of the nvme_fc_ctrl.
