If anyone has any objections, please let me know. ------------------ From: Michael Marineau commit e0d6cb9cd3a3ac8a3b8e5b22b83c4f8619786f22 upstream. This driver adds an attribute to the existing virtio device so a CHANGE event is required in order udev rules to make use of it. The ADD event happens before this driver is probed and unlike a more typical driver like a block device there isn't a higher level device to watch for.
