Subject: [PATCH tip/core/rcu 13/23] torture: Abstract out console-log error detection
Date: Mon, 22 Jun 2020 17:37:42 -0700	[thread overview]
Message-ID: <20200623003752.26872-13-paulmck@kernel.org> (raw)
In-Reply-To: <20200623003731.GA26717@paulmck-ThinkPad-P72>

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

This commit pulls the simple pattern-based error detection from the
console log into a new console-badness.sh file.  This will enable future
commits to end a run on the first error.

Signed-off-by: Paul E. McKenney <paulmck@kernel.org>
