Subject: KVM: selftests: implement an unchecked version of vcpu_ioctl()
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=7e50c424f8e2315182540a32edb6f19024d26c8b;p=openwrt%2Fstaging%2Fblogic.git

KVM: selftests: implement an unchecked version of vcpu_ioctl()

In case we want to test failing ioctls we need an option to not
fail. Following _vcpu_run() precedent implement _vcpu_ioctl().
