Subject: [PATCH RFC 0/2] Tests for preemptoff and irqsoff tracers
Date:   Thu, 17 May 2018 18:59:00 -0700
Message-Id: <20180518015902.131427-1-joelaf@google.com>
Sender: linux-kernel-owner@vger.kernel.org

From: "Joel Fernandes (Google)" <joel@joelfernandes.org>

Hi,
Here is test code and kselftest for testing the preemptoff and irqsoff
tracers. I am posting it separately just for early feedback since its
the first time I'm writing a kselftest.

I am planning to include these tests in the next series posting of
"Centralize and unify usage of preempt/irq tracepoints" [1]

By the way, other than these I have also completed testing with Ingo's
locking API test suite for [1]. I will include these and other results
in the v7 posting of [1].
