Not checked till now. I just was thinking about the basicapproach. I could either check the block_device_operations like you suggested or I could verify that the gendisk pointer is already in our devmap and therefor belongs to the DASD driver.
The ops pointer check is simpler and cheaper, so I'd suggest that.
