I guess we would receive just as many patches as we do today :) > @@ -8079,7 +8079,6 @@ F: Documentation/devicetree/bindings/gpu/ > F: Documentation/gpu/ > F: drivers/gpu/drm/ > F: drivers/gpu/vga/ > -F: rust/kernel/drm/ > F: include/drm/drm > F: include/linux/vga* > F: include/uapi/drm/ That's not really what I meant, what I meant was that rust/kernel/drm/ is the only thing I'm really interested on, but we don't need to maintain it if it makes more sense to do so separately. BTW, we should probably add to drm-misc X: drivers/gpu/drm/nova because we have a catch-all at the moment. Maxime
