Waiman Long 7fa0dacbaf mm/memcg: fix incorrect flushing of lruvec data in obj_stock ... When mod_objcg_state() is called with a pgdat that is different from that in the obj_stock, the old lruvec data cached in obj_stock are flushed out. Unfortunately, they were flushed to the new pgdat and so the data go to the wrong node. This will screw up the slab data reported in /sys/devices/system/node/node*/meminfo. Fix that by flushing the data to the cached pgdat instead.
