函数名称：A system can have three types of NUMA topology:* NUMA_DIRECT: all nodes are directly connected, or not a NUMA system* NUMA_GLUELESS_MESH: some nodes reachable through intermediary nodes* NUMA_BACKPLANE: nodes can reach other nodes through a backplane* The

函数原型：static void init_numa_topology_type(void)

返回类型：void

参数：无

1523  n等于sched_max_numa_distance
1525  如果sched_domains_numa_levels小于等于2则
1526  sched_numa_topology_type等于NUMA_DIRECT
1527  返回
1530  for_each_online_node(a)
1531  for_each_online_node(b)
1533  如果node_distance(a, b)小于n则继续下一循环
1537  for_each_online_node(c)
1538  如果node_distance(a, c)小于n且node_distance(b, c)小于n则
