Subject: [PATCH v5.10 1/2] torture: Exclude "NOHZ tick-stop error" from fatal errors
Date: Fri, 30 Dec 2022 15:32:13 +0000 [thread overview]
Message-ID: <20221230153215.1333921-1-joel@joelfernandes.org> (raw)
From: "Paul E. McKenney" <paulmck@kernel.org>
commit 8d68e68a781db80606c8e8f3e4383be6974878fd upstream.
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.
