  "message": "mm, vmscan: make zone_reclaimable_pages more precise\n\nzone_reclaimable_pages() is used in should_reclaim_retry() which uses it\nto calculate the target for the watermark check.  This means that\nprecise numbers are important for the correct decision.\nzone_reclaimable_pages uses zone_page_state which can contain stale data\nwith per-cpu diffs not synced yet (the last vmstat_update might have run\n1s in the past).\n\nUse zone_page_state_snapshot() in zone_reclaimable_pages() instead.\nNone of the current callers is in a hot path where getting the precise\nvalue (which involves per-cpu iteration) would cause an unreasonable\noverhead.\n\nSigned-off-by: Michal Hocko \u003cmhocko@suse.com\u003e\nSigned-off-by: Tetsuo Handa \u003cpenguin-kernel@I-love.SAKURA.ne.jp\u003e\nSuggested-by: David Rientjes \u003crientjes@google.com\u003e\nAcked-by: David Rientjes \u003crientjes@google.com\u003e\nAcked-by: Hillf Danton \u003chillf.zj@alibaba-inc.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n",
