Subject: [PATCH 15/24] mm/list_lru.c: Rename kvfree_rcu() to local variant
Date: Mon, 27 Apr 2020 13:11:04 +0200 [thread overview]
Message-ID: <20200427111113.5956-15-urezki@gmail.com> (raw)
In-Reply-To: <20200427111113.5956-1-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. So we
temporarily rename it and remove it in a later commit.
