Keita Suzuki 50181346e6 devices: vhost-user: block: Add hot-resizing feature in vhost-user block ... Current implementation does not allow hot-resizing feature to be used in vhost-user block devices because the backend device cannot notify the frontend that the device configuration has changed. Fix this by adding and establishing the backend to frontend vhost-user message connection to the vhost-user block backend, send the HANDLE_CONFIG_CHANGE_MSG to the frontend, and send interrupt to the guest kernel from the frontend device when receiving the message.
