[PATCH RFC 0/3] virtio: add new notify() callback to virtio_driver
Hi, when an active virtio block device is hot-unplugged from a KVM guest, running affected guest user applications are not aware of any errors that occur due to the lost device. This patch-set adds code to avoid further request queueing when a lost block device is detected, resulting in appropriate error info. On System z there exists no handshake mechanism between host and guest when a device
