malloc() itself can't do this, unless malloc(M_WAITOK) has been broken. Thousands of callers depend on malloc(M_WAITOK) not returning NULL, and malloc.9 still documents this behaviour. You may be thinking of mbuf allocation. It is confusingly different, starting with the no-wait flag being spelled differently (M_NOWAIT).
