How does that automatic process decide that a patch should be backported? drm and i915 are very fast moving targets so unintended side effects from backported patches is a real possibility. So I would recommend against backporting anything that isn't fixing a real issue affecting users. We do try to add the cc:stable to such patches. -- Ville Syrjälä Intel OTC _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx https://lists.freedesktop.org/mailman/listinfo/dri-devel
