From d1da396447096c919a1d80e2426f2ed019014915 Mon Sep 17 00:00:00 2001 From: Paolo Bonzini Date: Thu, 13 Feb 2020 18:24:48 +0100 Subject: [PATCH] KVM: x86: fix incorrect comparison in trace event [ Upstream commit 147f1a1fe5d7e6b01b8df4d0cbd6f9eaf6b6c73b ] The "u" field in the event has three states, -1/0/1. Using u8 however means that comparison with -1 will always fail, so change to signed char.
