[PATCH 3/3] mem-hotplug: fix potential race while building zonelist for new populated zone
Make "zone->present_pages gets increased" and "building zonelist" an atomic operation to prevent possible race. It is merely a theoretical race: after new zone gets populated, its pages might be allocated by others before itself building zonelist. Besides, atomic operation ensures alloc_percpu() will never fail... 17 May 2010 04:47
