Subject: [PATCH v4 0/4] virgl: fence fd support
This series implements fence support for drm/virtio and
has been tested using qemu, kmscube and the below branches.
Rob Herring solved a reference counting issue and

changes have been included in the below commits to
keep the tree working at all commits.
