I think we can actually kill bdev_handle entirely. We can get the bdev from the bdev inode using I_BDEV already, so no need to store the bdev. We don't need the mode field as we known an exlusive open is equivalent to having a holder. So just store the older in file->private_data and the bdev_handle can be removed again.
