From 9c7757290c6d80c2f5bde6fa71d2c9fe2b331c8c Mon Sep 17 00:00:00 2001 From: Kazuya Saito Date: Fri, 29 Mar 2013 13:27:05 +0900 Subject: kvm-all: add kvm_ioctl, kvm_vm_ioctl, kvm_vcpu_ioctl tracepoints This patch adds tracepoints at ioctl to kvm. Tracing these ioctl is useful for clarification whether the cause of troubles is qemu or kvm.
