Jiang Liu 340175b7d1 mm/hotplug: free zone->pageset when a zone becomes empty ... When a zone becomes empty after memory offlining, free zone->pageset. Otherwise it will cause memory leak when adding memory to the empty zone again because build_all_zonelists() will allocate zone->pageset for an empty zone.
