Subject: [PATCH tip/core/rcu 08/18] rcutorture: Add 100-CPU configuration
Date: Fri, 14 Feb 2020 16:41:15 -0800
Message-ID: <20200215004125.16953-2-paulmck@kernel.org> (raw)
In-Reply-To: <20200215003634.GA16227@paulmck-ThinkPad-P72>

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

The small-system rcutorture configurations have served us well for a great
many years, but it is now time to add a larger one.  This commit does
just that, but does not add it to the defaults in CFLIST.  This allows
the kvm.sh argument '--configs "4*CFLIST TREE10" to run four instances
of each of the default configurations concurrently with one instance of
the large configuration.
