From: Chen Wandun <chenwandun@huawei.com> hulk inclusion category: feature bugzilla: https://gitee.com/openeuler/kernel/issues/I4SK3S CVE: NA -------------------------------- If vmcache_reclaim_s > 120, it will call shrink_page_cache_work after 120 seconds even shrinking is hard, that is shorter than vmcache_reclaim_s, deviating from the original intention of extending the interval. In order to solve this, shrink_page_cache_work should be call after vmcache_reclaim_s + 120.
