these work great!

e.g.

        if (bpf_cmp_likely(idx, <, NR_MAP_ELEMS))
                map_elems[idx] = i;

works fine.  since that's essentially the code that bpf_array_elem() was 
trying to replace, i'd rather just use the new bpf_cmp helpers than have 
the special array_elem helpers.

thanks,
