From: Juergen Gross Date: Thu, 3 Mar 2016 07:55:30 +0000 (+0100) Subject: silence affinity messages on suspend/resume X-Git-Tag: archive/raspbian/4.8.0-1+rpi1~1^2~1613 X-Git-Url: https://dgit.raspbian.org/?a=commitdiff_plain;h=10d70e7830f1051d9190b4a3b9be60bcabf3d27f;p=xen.git 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.
