They're not optimal, with mod_lruvec_state() doing the entire intersection - node, memcg, lruvec - and mod_memcg_lruvec_state() being a specific version that does not update the node. However, the usecases for mod_memcg_lruvec_state() are highly specific, so the function won't be widely used. As such, it received the longer name, and we get to keep the shorter mod_lruvec_state() for the much more widely used function.
