函数名称：mem_cgroup_update_lru_size - account for adding or removing an lru page*@lruvec: mem_cgroup per zone lru vector*@lru: index of lru list the page is sitting on*@zid: zone id of the accounted pages*@nr_pages: positive when adding or negative when removing*

函数原型：void mem_cgroup_update_lru_size(struct lruvec *lruvec, enum lru_list lru, int zid, int nr_pages)

返回类型：void

参数：

类型	参数	名称
struct lruvec *	lruvec
enum lru_list	lru
int	zid
int	nr_pages

mz等于container_of - cast a member of a structure out to the containing structure*@ptr: the pointer to the member.*@type: the type of the container struct this is embedded in.*@member: the name of the member within the struct.(lruvec, structmem_cgroup_per_node, lruvec)

1265

lru_size等于lru_zone_size[zid][lru]

1267

如果nr_pages小于0则lru_size加等于nr_pages

1270

size等于lru_size

1271

如果WARN_ONCE(size < 0, "%s(%p, %d, %d): lru_size %ld\n", __func__, lruvec, lru, nr_pages, size)则

1274

VM_BUG_ON(1)

1275

lru_size等于0

1278

如果nr_pages大于0则lru_size加等于nr_pages
