From 60ced4950c5059eff3f03027926eb5384f9923e1 Mon Sep 17 00:00:00 2001 From: "Paul E. McKenney" Date: Mon, 27 Oct 2014 16:04:35 -0700 Subject: rcu: Fix FIXME in rcu_tasks_kthread() This commit affines rcu_tasks_kthread() to the housekeeping CPUs in CONFIG_NO_HZ_FULL builds. This is just a default, so systems administrators are free to put this kthread somewhere else if they wish. Signed-off-by: Paul E.
