From 2bfe11c8fac96db4f94abbe818fbc964a6744130 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Llu=C3=ADs=20Vilanova?= Date: Mon, 19 Sep 2016 14:55:07 +0200 Subject: trace: Properly initialize dynamic event states in hot-plugged vCPUs MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Every time a vCPU is hot-plugged, it will "inherit" its tracing state from the global state array. That is, if *any* existing vCPU has an event enabled, new vCPUs will have too.
