Subject: [PATCH tip/core/rcu 3/4] rcutorture: Check for self-detected stalls
Date: Tue, 23 Feb 2016 21:17:15 -0800	[thread overview]
Message-ID: <1456291036-19545-3-git-send-email-paulmck@linux.vnet.ibm.com> (raw)
In-Reply-To: <20160224051630.GA18874@linux.vnet.ibm.com>

The current scripts parse console output only for cases where one CPU
detect a stall on some other CPU or task.  This commit therefore adds
checks for self-detected stalls.
