Subject: [PATCH tip/core/rcu 2/8] rcu-tasks: Mark variables static
Date: Thu, 17 Sep 2020 14:07:38 -0700	[thread overview]
Message-ID: <20200917210744.2995-2-paulmck@kernel.org> (raw)
In-Reply-To: <20200917210652.GA31242@paulmck-ThinkPad-P72>

From: "Paul E. McKenney" <paulmck@kernel.org>

The n_heavy_reader_attempts, n_heavy_reader_updates, and
n_heavy_reader_ofl_updates variables are not used outside of their
translation unit, so this commit marks them static.
