There will be a way to iterate through all of the pids.

It will probably be through a linked list of struct pid, but
it may be an in order traversal of some pid related data structure.

I was hoping for a moment I might be able to only implement one
struct pid, but I need some method to perform a reverse lookup
from struct pid to a (struct pid_namespace, pid_t) pair to
properly implement pid_nr().  A linked list of struct pid entries
is the obvious implementation.
