函数名称：__inc_numa_state

函数原型：void __inc_numa_state(struct zone *zone, enum numa_stat_item item)

返回类型：void

参数：

类型参数名称
struct zone *zone
enum numa_stat_itemitem
942  __percpu乘pcp等于CPU热/冷页帧列表
943  __percpu乘p等于vm_numa_stat_diff加item
946  v等于__this_cpu_inc_return( * p)
948  如果此条件成立可能性小(为编译器优化)(v > NUMA_STATS_THRESHOLD)则
949  zone_numa_state_add(v, zone, item)
950  __this_cpu_write( * p, 0)
