McKenney" <paulmck@...ux.vnet.ibm.com> Subject: [PATCH tip/core/rcu 05/11] rcutorture: Test partial nohz_full= configuration From: "Paul E. McKenney" <paulmck@...ux.vnet.ibm.com> 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.
