From 5d0b024973027556b48a09bb36b55dc853ec7c6e Mon Sep 17 00:00:00 2001 From: "Paul E. McKenney" Date: Mon, 10 Nov 2014 08:07:08 -0800 Subject: [PATCH] rcu: Don't bother affinitying rcub kthreads away from offline CPUs When rcu_boost_kthread_setaffinity() sees that all CPUs for a given rcu_node structure are now offline, it affinities the corresponding RCU-boost ("rcub") kthread away from those CPUs. This is pointless because the kthread cannot run on those offline CPUs in any case. This commit therefore removes this unneeded code. Signed-off-by: Paul E.
