Let's handle it similar to x86 ACPI PCI code and don't use a timer. Instead, remember if an unplug request is pending and keep it pending for eternity. (a follow up patch will process the request on reboot). We expect that a guest that is up and running, will process the unplug request and trigger the unplug. This is normal operation, no timer needed. If the guest does not react, this usually means something in the guest is going wrong. Simply removing the device after 30 seconds does not really sound like a good idea. It might sometimes be wanted, but I consider this rather an "opt-in" decision as it might harm a guest not prepared for it. If we ever actually want a "forced/surprise removal", we will have to implement something on top of the existing "device_del" framework. E.g. also x86 might want to do a forced/surprise removal of PCI devices under some conditions. "device_del X, forced=true" could be an option and will require changes to the hotplug handler infrastructure. This will then move the responsibility on when to do a forced removal to a higher level. Doing a forced removal right now over-complicates things and doesn't really seem to be required. Let's allow to send multiple requests.
