[PATCH tip/core/rcu 05/11] rcutorture: Test partial nohz_full= configuration

From: Paul E. McKenney
Date: Thu Aug 28 2014 - 15:14:30 EST


From: "Paul E. McKenney" <paulmck@xxxxxxxxxxxxxxxxxx>

The current set of tests covers only cases where either all possible CPUs
are nohz_full= CPUs or none of them are. Because there have been some
recent bug escapes in cases where only some of the CPUs are nohz_full=
CPUs, this commit add a configuration where only half of the CPUs are
nohz_full= CPUs.
