list_lru_walk_node() invokes __list_lru_walk_one() with -1 as the memcg_idx parameter. The same can be achieved by list_lru_walk_one() and passing NULL as memcg argument which then gets converted into -1. This is a preparation step when the spin_lock() function is lifted to the caller of __list_lru_walk_one(). Invoke list_lru_walk_one() instead __list_lru_walk_one() when possible.
