Subject: [PATCH tip/core/rcu 01/12] rcu: Remove rcu_swap_protected()
Date: Mon, 9 Dec 2019 20:07:30 -0800 [thread overview]
Message-ID: <20191210040741.2943-1-paulmck@kernel.org> (raw)
In-Reply-To: <20191210040714.GA2715@paulmck-ThinkPad-P72>
From: "Paul E. McKenney" <paulmck@kernel.org>
Now that the calls to rcu_swap_protected() have been replaced by
rcu_replace_pointer(), this commit removes rcu_swap_protected().
