I know most of you understand this, but I just wanted to make it
clear:

The kernel should simply ignore any bi_rec it doesn't know about - and
does.  The question is, how can we guarantee that the kernel doesn't
know about that bi_rec?  The answer is that we need to reserve at
least one (or several, under Ben's plan) bi_rec types that are
guaranteed not to be used by the kernel.  That's all I was trying to
say.
