    I think that it is exactly what holders/slaves do - displaying device
    hierarchy. So application can check which underlying device are related
    and ask them for more info if needed (=> with system specific call,
    it can be simple sysfs attribute, ioctl, whatever).

    So the only request here is to keep these symlinks correct, nothing more.
    Or am I missing anything?
