Name:Update LRU sizes after isolating pages. The LRU size updates must* be complete before mem_cgroup_update_lru_size due to a santity check.
Proto:static __always_inline void update_lru_sizes(struct lruvec *lruvec, enum lru_list lru, unsigned long *nr_zone_taken)
Type:void
Parameter:
| Type | Parameter | Name |
|---|---|---|
| struct lruvec * | lruvec | |
| enum lru_list | lru | |
| unsigned long * | nr_zone_taken |
| 1616 | When zid < MAX_NR_ZONES cycle |
| 1617 | If Not nr_zone_taken[zid] Then Continue |
| 1620 | __update_lru_size(lruvec, lru, zid, - nr_zone_taken[zid]) |
| 1622 | mem_cgroup_update_lru_size(lruvec, lru, zid, - nr_zone_taken[zid]) |
| Name | Describe |
|---|---|
| isolate_lru_pages | pgdat->lru_lock is heavily contended. Some of the functions that* shrink the lists perform better by taking out a batch of pages* and working on them outside the LRU lock.* For pagecache intensive workloads, this function is the hottest |
