s/every/& generic/. Other than that, seconded. BTW, one of the pending
changes is taking the last more or less generic ioctl (HDIO_GETGEO) into
a separate method...

->ioctl() is for driver-specific crud; stuff that won't be used by
any generic application. "Make a cuckoo jump out of drive and sing
'1000 bottles of beer'" is a valid ioctl. "Get drive size" isn't.
