From 6530b3f4c5043aa8ef66faa8296291b1ea6ba2eb Mon Sep 17 00:00:00 2001 From: "Paul E. McKenney" Date: Thu, 12 Mar 2015 11:42:48 -0700 Subject: [PATCH] rcutorture: Exchange TREE03 and TREE08 NR_CPUS, speed up CPU hotplug TREE03 has been especially effective at finding bugs lately. This commit makes it even more effective by speeding up its CPU hotplug testing and increasing its NR_CPUs from 8 to 16. TREE08's NR_CPUS is decreased from 16 to 8 in order to maintain the same test duration. Signed-off-by: Paul E.
