If a block_device is a partition, then it's kobject is bdev->bd_part->kobj otherwise (if it is a full device), the kobject is bdev->bd_disk->kobj As md wants back-links to the correct object (whether partition or not), we need to respect this difference... (Thus current code shows a link to the whole device, whether we are using a partition or not, which is wrong).
