Subject: [PATCH tip/core/rcu 09/28] torture: Exclude "NOHZ tick-stop error" from fatal errors
Date: Thu,  5 Nov 2020 15:47:00 -0800	[thread overview]
Message-ID: <20201105234719.23307-9-paulmck@kernel.org> (raw)
In-Reply-To: <20201105234658.GA23142@paulmck-ThinkPad-P72>

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

The "NOHZ tick-stop error: Non-RCU local softirq work is pending"
warning happens frequently and appears to be irrelevant to the various
torture tests.  This commit therefore filters it out.

If there proves to be a need to pay attention to it a later commit will
add an "advice" category to allow the user to immediately see that
although something happened, it was not an indictment of the system
being tortured.
