Subject: [PATCH v3 14/19] checkpatch: Remove checks relating to [smp_]read_barrier_depends()
Date: Fri, 10 Jul 2020 17:51:58 +0100 [thread overview]
Message-ID: <20200710165203.31284-15-will@kernel.org> (raw)
In-Reply-To: <20200710165203.31284-1-will@kernel.org>
The [smp_]read_barrier_depends() macros no longer exist, so we don't
need to deal with them in the checkpatch script.
Acked-by: Paul E. McKenney <paulmck@kernel.org>
