Right you are. Too bad. Just bolting an access_ok() on the
front of this code let me get away with not messing with the
existing code.
Keeping patches minimal is easier if they don't have to work ;).
As long as I have to mess with the 'R' parsing code anyway,
might as well use copy_from_user() and clean up these few lines
of code as best I can.
Another patch will be forthcoming.
