https://bugzilla.redhat.com/show_bug.cgi?id=573210 ptrace_report_clone() uses child->pid, this is obviously wrong unless the tracer is from the global namespace. Change it to use task_pid_vnr(). This is still not right, we should use the tracer's namespace, not parent's. But this matches upstream, and at least this works if they are from the same namespace.
