函数原型：static void show_numa_info(struct seq_file *m, struct vm_struct *v)

返回类型：void

参数：

类型参数名称
struct seq_file *m
struct vm_struct *v
3558  如果IS_ENABLED(CONFIG_FOO) evaluates to 1 if CONFIG_FOO is set to 'y' or 'm',* 0 otherwise.(CONFIG_NUMA)则
3559  counters等于private
3561  如果非counters则返回
3564  如果flags按位与vm_struct is not fully initialized 则返回
3567  smp_rmb()
3569  memset(counters, 0, nr_node_ids * sizeof(unsignedint))
3571  以nr小于nr_pages循环counters[page_to_nid(pages[nr])]自加
3574  for_each_node_state(nr, N_HIGH_MEMORY)
3575  如果counters[nr]则seq_printf(m, " N%u=%u", nr, counters[nr])
