Hi Thomas,
That change just want to make sure below two buffers have enough space when configure RTE_MAX_NUMA_NODES=1.
/* construct an invalid socket mask with 2 megs on each socket plus
* extra 2 megs on socket that doesn't exist on current system */
char invalid_socket_mem[SOCKET_MEM_STRLEN];
char buf[SOCKET_MEM_STRLEN];> /* to avoid copying string onto itself */
Thanks,
Phil Yang
