Your patch looks wrong (ook ook! 8)) - if you build without BUG enabled you
don't make various function calls with your change. BUG_ON has the C nasty
assert() does that makes it a horrible horrible idea and its unfortunate
it got put in.

        BUG_ON(function(x,y))

ends up not causing function to be called when not debugging

The classic C mess people get into is similar with things like

        assert(x++ == 4);
