Subject: [PATCH 01/18] mm/list_lru.c: Rename kvfree_rcu() to local variant
Date: Sun, 29 Mar 2020 22:32:31 -0400 [thread overview]
Message-ID: <20200330023248.164994-2-joel@joelfernandes.org> (raw)
In-Reply-To: <20200330023248.164994-1-joel@joelfernandes.org>
From: "Uladzislau Rezki (Sony)" <urezki@gmail.com>
Rename kvfree_rcu() function to the kvfree_rcu_local()
one. The aim is to introduce the public API that would
conflict with this one.
