memcg: fix LRU accounting for SwapCache
Now, a page can be deleted from SwapCache while do_swap_page(). memcg-fix-swap-accounting-leak-v3.patch handles that, but, LRU handling is still broken. (above behavior broke assumption of memcg-synchronized-lru patch.) This patch is a fix for LRU handling (especially for per-zone counters). At charging SwapCache, - Remove page_cgroup from LRU if it's not used. - Add page cgroup to LRU if it's not linked to.
