Subject[PATCH tip/core/rcu 4/4] locktorture: Forgive apparent unfairness if CPU hotplug
Date
From: "Paul E. McKenney" <paulmck@kernel.org>

If CPU hotplug testing is enabled, a lock might appear to be maximally
unfair just because one of the CPUs was offline almost all the time.
This commit therefore forgives unfairness if CPU hotplug testing was
enabled.
