    I believe his first name started with an L and ended with an s ;-)

    Seriously the kmalloc(0) pointer allowed us to detect cases in which
    people tried to store into objects allocated with kmalloc(0).

    If we would just return NULL then we would not be able to distinguish it
    from a failure (that is what I initially had).
