I'm correcting my own post :-)

What we really want is:

prio: 0 .. [MAX_RT_PRIO - MAX_USER_RT_PRIO] .. MAX_RT_PRIO .. MAX_PRIO

                                                    |---- nice -------|
                         |------ user RT prio ------|
      |------------ kernel RT prio -----------------|

Remember, 0 is of highest priority.
