How about this?

if (txc->modes & ADJ_OFFSET) {
	if (txc->constant == INT32_MIN) {

}

This looks like magic behavior. Sort of a "knock twice and then say the
password" interface. I don't see why that would be better then adding a
clear new mode flag?

That said, I'm somehow against the idea of using the adjtimex syscall
for that purpose.

Could you expand on why you don't like this?
