I think we can't prevent other modules from using the API. But 3rd-party modules deal with CPU virtualization extensions today won't live with KVM today, anyway. And between not living together with KVM and breaking kdump/reboot, and not living together with KVM and making kdump and reboot working, I the the latter looks better. But I see this as an orthogonal issue. If we include a "CPU virtualization extensions core API" in the future, it could simply keep the same emergency_virt_disable() API available for emergency_restart and kdump. -- Eduardo -- To unsubscribe from this list: send the line "unsubscribe kvm" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html
