From a4cca3b419a5081788bb7559023159e3147f66f0 Mon Sep 17 00:00:00 2001 From: Heiko Carstens Date: Tue, 5 May 2015 09:39:08 +0200 Subject: [PATCH] KVM: remove pointless cpu hotplug messages On cpu hotplug only KVM emits an unconditional message that its notifier has been called. It certainly can be assumed that calling cpu hotplug notifiers work, therefore there is no added value if KVM prints a message. If an error happens on cpu online KVM will still emit a warning. So let's remove this superfluous message.
