    exit: reparent: cleanup the changing of ->parent · 57a05918

    1. Cosmetic, but "if (t->parent == father)" looks a bit confusing.
       We need to change t->parent if and only if t is not traced.
    
    2. If we actually want this BUG_ON() to ensure that parent/ptrace
       match each other, then we should also take ptrace_reparented()
       case into account too.
    
    3. Change this code to use for_each_thread() instead of deprecated
       while_each_thread().
