Heinz Graalfs e75279c4fb virtio_ccw: introduce device_lost in virtio_ccw_device ... When a device is lost, the common I/O layer calls the notification handler with CIO_GONE: In that event, flag device_lost as true. In case the device had been flagged as lost when the remove/offline callbacks are called, call the new virtio_break_device() function prior to invoking device_unregister(). This avoids hangs of I/O triggered via the device unregistration callbacks.
