McKenney" Date: Mon, 16 Jul 2012 10:42:38 +0000 Subject: rcu: Use smp_hotplug_thread facility for RCUs per-CPU kthread Bring RCU into the new-age CPU-hotplug fold by modifying RCU's per-CPU kthread code to use the new smp_hotplug_thread facility. [ tglx: Adapted it to use callbacks and to the simplified rcu yield ] Signed-off-by: Paul E. McKenney Cc: Peter Zijlstra Cc: Srivatsa S.
