From 3721bc1d3ed9940b17791805b7ee3a4743295d12 Mon Sep 17 00:00:00 2001 From: "Paul E. McKenney" <paulmck@linux.vnet.ibm.com> Date: Thu, 21 Jul 2011 16:00:17 -0700 Subject: [PATCH] rcu: Allow rcutorture's stat_interval parameter to be changed at runtime When rcutorture is compiled directly into the kernel (instead of separately as a module), it is necessary to specify rcutorture.stat_interval as a kernel command-line parameter, otherwise, the rcu_torture_stats kthread is never started. However, when working with the system after it has booted, it is convenient to be able to change the time between statistic printing, particularly when logged into the console. This commit therefore allows the stat_interval parameter to be changed at runtime. Signed-off-by: Paul E.
