Eric, Pavel, could you review 1/2 ? (documentation only). It is based on the code inspection, I didn't bother to verify that my understanding matches the reality ;)

So far only the documentation fix. I'll write another email (hopefully with the patch), afaics at least setns() doesn't play well with PR_SET_CHILD_SUBREAPER. Contrary to what I thought zap_pid_ns_processes() looks fine, but it seems only by accident. Unless I am totally confused, wait for "nr_hashed == init_pids" could be removed after 0a01f2cc390e10633a "pidns: Make the pidns proc mount/ umount logic obvious". However, now that setns() + fork() can inject a task into a child namespace, we need this code again for another reason. I _think_ we can actually remove it and simplify free_pid() as well, but lets discuss this later and fix the wrong/confusing documentation first. 2/2 looks "obviously correct", but I'll appreciate your review anyway.
