Looking around at this, it turns out that a great example of this kind of legacy issue is the debug_mutex stuff. It uses "struct thread_info *" as the owner pointer, and there is _no_ existing reason for it. In fact, in every single place it actually wants the task_struct, and it does task_thread_info(task) just to convert it to the thread-info, and then converts it back with "ti->task". So the attached patch seems to be the right thing to do regardless of this whole discussion.
