As we stop storing pid_t's and move to storing struct pid *. We
need a way to get the pid_t from the struct pid to report to user
space what we have stored.
Having a clean well defined way to do this is especially important
as we move to multiple pid spaces as may need to report a different
value to the caller depending on which pid space the caller is in.
