File 0036-tools-kvm_stat-fix-crash-when-filtering-out-all-non-.patch of Package kvm_stat.12295
From 0731f3872508a8c4a7df9f77eeebd5046bffcbf8 Mon Sep 17 00:00:00 2001 From: Stefan Raspl <stefan.raspl@de.ibm.com> Date: Mon, 5 Feb 2018 13:59:57 +0100 Subject: [PATCH 36/43] tools/kvm_stat: fix crash when filtering out all non-child trace events When we apply a filter that will only leave child trace events, we receive a ZeroDivisionError when calculating the percentages. In that case, provide percentages based on child events only. To reproduce, run 'kvm_stat -f .*[\(].*'.
