VirtualBox upstream has added a new ioctl to their out of tree driver
implementring the /dev/vboxguest device in the VirtualBox 6.1.x series.
Without this ioctl being supported automatic resizing of the guest
resolution to match the Window size does not work when using the VMSVGA
virtual GPU which is the default GPU for new VMs under VirtualBox 6.1.x
.
This series has been posted upstream here:
https://lore.kernel.org/lkml/20200520195440.38759-1-hdegoede@redhat.com/
This patch series adds support for the new ioctl, fixing the resizing
issue.
