I believe to get this right we need a factor of pid_nr: pid_t __pid_nr(struct pid_namespace *ns, struct pid *pid) That we can pass the pid_namespace from the super block of the mount to handle the proc case. This is a case I have wanted to avoid but in this instance I don't see any other way to get the code correct. i.e. Since the pid namespace of /proc gets set at mount time who you are should not vary the result it gives.
