From 80be9246955a2dc65d3d97ba731de682838277b7 Mon Sep 17 00:00:00 2001 From: Juergen Gross Date: Thu, 3 Mar 2016 08:55:30 +0100 Subject: [PATCH] silence affinity messages on suspend/resume When taking cpus offline for suspend or bringing them online on resume again the scheduler might issue debug messages when temporarily breaking vcpu affinity or restoring the original affinity settings. The resume message can be removed completely, while the message when breaking affinity should only be issued if the breakage is permanent.
