I agree with Jeff that Tejun's tool would be the right place. And there's always udev... But the question is whether it's worth the hassle since there a many of these devices out there and it is unclear whether treating them as non-rotational is a win. If you can provide some compelling performance improvement numbers for a particular device we can look into adding a quirk for it. -- Martin K.
