How much private ioctls do you need actually ? I assume that for sending raw commands you use SG_IO already...
BTW it would be really nice if the various raid controller drivers could come up with a joint common IOCTL api since it seems every raid controller driver right now has a largely overlapping but yet different set of ioctls. [unhandled content-type:application/pgp-signature]
