    Well, kmalloc(0) has always been legal and traditionally returned a
    pointer to a smallest non-zero sized object. We did try to make
    kmalloc(0) illegal for a while but ended up fixing up a bunch of
    call-sites for little or no gain. I did propose that kmalloc(0) should
    return NULL but Linus and others pointed out that we can do better and
    not mix up out-of-memory and zero-sized allocations.
