I don't like this even more.
Pid namespaces are hierarchical _and_ anonymous, so simply set of numbers doesn't describe the final object.
struct pid isn't special, it's just another invariant if you like as far as C/R is concerned, but system call is made special wrt pids.
What will be in an image? I hope "struct kstate_image_pid" with several numbers and with references to such object from other places, so it seems natural to do alloc_pid() with needed numbers and that attach new shiny pid to where needed. But this clone_pid is only for task_struct's pids.
