------------------------------------------------------ From: Yafang Shao laoar.shao@gmail.com Subject: mm/memcontrol: fix wrong statistics in memory.stat
When we calculate total statistics for memcg1_stats and memcg1_events, we use the the index 'i' in the for loop as the events index. Actually we should use memcg1_stats[i] and memcg1_events[i] as the events index.
