I did have a request for someone doing a backup application over cifs to return creation time so at least this would make sense. -- Thanks, Steve -- To unsubscribe from this list: send the line "unsubscribe linux-ext4" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
