Sahitya Tummala a48542e8b4 mm/list_lru.c: fix list_lru_count_node() to be race free ... commit 2c80cd57c7 upstream. list_lru_count_node() iterates over all memcgs to get the total number of entries on the node but it can race with memcg_drain_all_list_lrus(), which migrates the entries from a dead cgroup to another. This can return incorrect number of entries from list_lru_count_node(). Fix this by keeping track of entries per node and simply return it in list_lru_count_node().
