Subject: [dm-devel] [PATCH 39/45] block: remove the partno field from struct hd_struct
Date: Tue, 24 Nov 2020 14:27:45 +0100 [thread overview]
Message-ID: <20201124132751.3747337-40-hch@lst.de> (raw)
In-Reply-To: <20201124132751.3747337-1-hch@lst.de>
Just use the bd_partno field in struct block_device everywhere.
