From 9e62b0efdcead5b66c0c006df2f19a449b22cf08 Mon Sep 17 00:00:00 2001 From: "Paul E. McKenney" <paulmck@linux.vnet.ibm.com> Date: Mon, 21 Jul 2014 13:13:35 -0700 Subject: [PATCH] rcutorture: Test partial nohz_full= configuration 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.
