[RFC v3 1/6] virtio: Add bool to VirtQueueElement

Posted by Jonah Palmer 1 year, 10 months ago

Add the boolean 'filled' member to the VirtQueueElement structure. The
use of this boolean will signify if the element has been written to the
used / descriptor ring or not. This boolean is used to support the
VIRTIO_F_IN_ORDER feature.
