Subject[PATCH] mm/list_lru.c: remove kvfree_rcu_local()
From
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.
