函数名称:The inactive anon list should be small enough that the VM never has* to do too much work.* The inactive file list should be small enough to leave most memory* to the established workingset on the scan-resistant active list,
函数原型:static bool inactive_is_low(struct lruvec *lruvec, enum lru_list inactive_lru)
返回类型:bool
参数:
类型 | 参数 | 名称 |
---|---|---|
struct lruvec * | lruvec | |
enum lru_list | inactive_lru |
2211 | active_lru等于inactive_lru加LRU_ACTIVE |
2216 | inactive等于lruvec_page_state(lruvec, NR_LRU_BASE + inactive_lru) |
2217 | active等于lruvec_page_state(lruvec, NR_LRU_BASE + active_lru) |
2219 | gb等于inactive加active右移30减PAGE_SHIFT determines the page size 位 |
2220 | 如果gb则inactive_ratio等于_sqrt - computes the integer square root*@x: integer of which to calculate the sqrt* Computes: floor(sqrt(x)) |
2222 | 否则inactive_ratio等于1 |
2225 | 返回:inactive乘inactive_ratio小于active |
