From 8170580a16ad989a2bc3698ba53e647922607aaf Mon Sep 17 00:00:00 2001 From: Tony Jones Date: Fri, 21 Feb 2014 12:17:28 -0800 Subject: [PATCH] Fix: correctly version kvm events to build against v3.0 kernel Cleanly build against v3.0 kernel. I didn't add versioning for mainline commit 0d460ffc as it's build compatible.
