Yes, all cases setting .si_pid should set it using the pid_ns of the
recipient. Numerous other cases look wrong too, though maybe Sukadev has
outstanding patches for those already? (It's been a while since we went
around on this, and I am fuzzy on some of the details.) ptrace_notify,
ptrace_signal, sys_kill, do_tkill all look wrong to me. (Only sys_kill
needs to solve the multiple-recipients problem.)
