[PATCH tip/core/rcu 13/17] mm/list_lru.c: Rename kvfree_rcu() to local variant
From: paulmck
Date: Wed Jun 24 2020 - 16:12:47 EST
From: "Uladzislau Rezki (Sony)" <urezki@xxxxxxxxx>
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.
