When you call "free()", that has a requisite parameter: the data to
free. If you don't supply it, we should BUG_ON(), right?

No. Instead we do the sane thing and just do

if (unlikely(ZERO_OR_NULL_PTR(x)))

and it's all good.

Again, what is the *advantage* of being a complete ass-wipe and saying
"f*ck you", when it's less code to just say "that didn't work"?

Because one of those BUG_ON's clearly did happen.

So exactly what is your excuse for killing the machine instead of just
saying "yeah, can't validate that"?
