From a7b7e1df892457935ec4f35ef9e9aa344758dbc9 Mon Sep 17 00:00:00 2001 From: Shakeel Butt Date: Wed, 24 Feb 2021 12:04:12 -0800 Subject: mm/list_lru.c: remove kvfree_rcu_local() The list_lru file used to have local kvfree_rcu() which was renamed by commit e0feed08ab41 ("mm/list_lru.c: Rename kvfree_rcu() to local variant") to introduce the globally visible kvfree_rcu(). Now we have global kvfree_rcu(), so remove the local kvfree_rcu_local() and just use the global one.
