    That logic is in allocate_slab() and if the higher order allocation
    fails, we fall-back to struct kmem_cache ->min order. That in turn is
    set up in calculate_sizes() to get_order(size) so it seems pretty
    unlikely to me the allocation is 800 bytes. Of course, I could be
    missing something here and there's a bug in oo_make() or oo_order().
