[PATCH tip/core/rcu 2/4] locktorture: Allow CPU-hotplug to be disabled via --bootargs

From: paulmck
Date: Fri Feb 14 2020 - 19:03:51 EST


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

The bootparam_hotplug_cpu() bash function was checking for CPU-hotplug
kernel-boot parameters from --bootargs, but that check was specific to
rcutorture ("rcutorture\.onoff_"). This commit therefore makes this
check also work for locktorture ("torture\.onoff_").

Note that rcuperf does not do CPU-hotplug operations, so it is not
necessary to make a similar change for rcuperf.
