McKenney <paulmck@xxxxxxxxxx> CommitterDate: Mon, 29 Jun 2020 11:59:25 -07:00 mm/list_lru.c: Rename kvfree_rcu() to local variant Rename kvfree_rcu() function to the kvfree_rcu_local() one. The purpose is to prevent a conflict of two same function declarations. The kvfree_rcu() will be globally visible what would lead to a build error. No functional change.
