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.

                          I won't rest till it's the best ...
