  ok, i take that back and claim the opposite - i misinterpreted the kernel's task_struct's real_parent member's purpose.
  
  that also means that the kernel doc is mildly misleading ("descendant" clearly refers to the current relationship after possible re-parenting, not the real ancestry at time of forking), but i suppose one is expected to know the exact definitions of the used terminology.
