After a quick look (I have to run now, so I could be completely wrong):
what about the task is not in the list *yet*. You use RCU ->
for_each_process_thread(), so there could be a race with attach_pid()
protected by tasklist_lock.
Not attach_pid(), that's irrelevant here.
But one line below in copy_process(): list_add_tail().
