Subject: [PATCH tip/core/rcu 01/18] rcutorture: Add KCSAN stubs
Date: Wed, 15 Apr 2020 10:30:43 -0700 [thread overview]
Message-ID: <20200415173100.9927-1-paulmck@kernel.org> (raw)
In-Reply-To: <20200415173037.GA9768@paulmck-ThinkPad-P72>
From: "Paul E. McKenney" <paulmck@kernel.org>
This commit adds stubs for KCSAN's data_race(), ASSERT_EXCLUSIVE_WRITER(),
and ASSERT_EXCLUSIVE_ACCESS() macros to allow code using these macros to
move ahead.
