Subject: [PATCH tip/core/rcu 1/5] rcu: Update rcutorture defaults
Date: Thu, 30 Aug 2012 11:45:08 -0700 [thread overview]
Message-ID: <1346352312-31987-1-git-send-email-paulmck@linux.vnet.ibm.com> (raw)
In-Reply-To: <20120830184448.GA31753@linux.vnet.ibm.com>
From: "Paul E. McKenney" <paul.mckenney@linaro.org>
A number of new features have been added to rcutorture over the years, but
the defaults have not been updated to include them. This commit therefore
turns on a couple of them that have proven helpful and trustworthy, namely
periodic progress reports and testing of NO_HZ.
