From 6e018968f8d384d84484eba8e4c90489a25d7095 Mon Sep 17 00:00:00 2001 From: Sebastian Andrzej Siewior Date: Fri, 17 Aug 2018 15:49:51 -0700 Subject: [PATCH] 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.
