"task_is_current()"? "current" means something totally different in the linux kernel: it means that the task is _this_ task. So the only sensible implementation of "task_is_current(task)" is to just make it return "task == current", but that's obviously not what the function wants to do. So it should be renamed. Something like "task_is_oncpu()" or whatever. I realize that the scheduler internally has that whole "rq->curr" thing, but that's an internal scheduler thing, and should not be confused with the overall kernel model of "current".
