No. There is EMPTY_TREE in use, but it's exactly what we expect. It's probably still a good idea to separate "global" variables from per-file ones. But I don't feel strongly about this, so if a re-roll is required (or somebody votes for underscore removal, including you), I'll remove the underscore. -- Duy -- To unsubscribe from this list: send the line "unsubscribe git" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
