you weren't entirely happy with the change because of the
possible (or, as you state, necessary) need to undo this. I
still think in the current shape the NULL checks are
pointless and hence would better go away. Re-introducing them
(adjusted to whatever shape the function may be in by that
time) is not that big of a problem. May I ask that you
explicitly clarify whether you actively NAK the patch, accept
it going in with Roger's R-b, or would be willing to ack it?

Thanks, Jan
