Each struct upid element of struct pid has to be initialized properly, i.e. its nr mst be allocated from appropriate pidmap and ns set to appropriate namespace. When allocating a new pid, we need to know the namespace this pid will live in, so the additional argument is added to alloc_pid(). On the other hand, the rest of the kernel still uses the pid->nr and pid->pid_chain fields, so these ones are still initialized, but this will be removed soon.
