For example, kuid_into_mnt() ultimately calls map_id_down(). That is, id visible inside user namespace is mapped to host (if observer is in init_user_ns, IIUC). But fsuid_into_mnt() ultimately calls map_id_up(). That's take a kuid and map it into the user_namespace. So both the helpers end with into_mnt() but one maps id down and other maps id up. I found this confusing and was wondering how should I visualize it. So thought of asking you. Is this intentional or can naming be improved so that *_into_mnt() means one thing (Either map_id_up() or map_id_down()). And vice-a-versa for *_from_mnt().
