The new version is to follow Vlastimil's suggestion, which fix by checking the new_nodes value in function get_nodes. And I just split them to small patches for easy to review and discussion. For more detail, please look into each patches. Change logs of v2: * fix get_nodes's mask miscalculation * remove redundant check in get_nodes * fix the check of nodemask from user - per Vlastimil Any comment and complain is welome.
