Subject: mm/list_lru.c: pass struct list_lru_node* as an argument to __list_lru_walk_one()
__list_lru_walk_one() is invoked with struct list_lru *lru, int nid as the
first two argument. Those two are only used to retrieve struct
list_lru_node. Since this is already done by the caller of the function
for the locking, we can pass struct list_lru_node* directly and avoid the
dance around it.
