block: pass a gendisk to bdev_add_partition
bdev_add_partition can only operate on the whole device. Make that clear by passing a gendisk instead of a block_device. Signed-off-by: Christoph Hellwig <hch@lst.de> Link: https://lore.kernel.org/r/20210810154512.1809898-3-hch@lst.de Signed-off-by: Jens Axboe <axboe@kernel.dk>
