Reserving a generous ioctl range without any clear interface will make some people nervous. If you can not specify the interface now, try to separate the generic/specific part of it and use sub-ioctl for the really scary things as it will make the future life easier. If you have some pointers to the existing code, that may help too. -- Ueimor
