Not necessarily disagreeing, but I don't think it's helpful to set the bar impossibly high. Even static_key doesn't have "exactly *zero*" impact. Let's stick to as minimal as possible when not in use and reasonable in use.
For !CONFIG_MEMCG_KMEM, it should be exactly zero. No need to play games with static_key.
