Subject: [PATCH v2] mm/vmscan.c: 'lru' may be used without initialized after
 the patch "3abf380..." in next-20130607 tree


'lru' may be used without initialized, so need regressing part of the
related patch.

The related patch:
  "3abf380 mm: remove lru parameter from __lru_cache_add and lru_cache_add_lru"
