yeah i agree. Group limit(s) should not be changing so frequently. > > perhaps > > - Move p->load_weight to a class structure > > Sounds like a good idea if you can do it - but if it's per-process, > how would it fit in the class structure? p->load_weight essentially depends on two things: - nice value or static priority (which is per process, already present in task_struct) - class limit (which is per class) So in theory we can eliminate the load_weight field in task_struct and compute it at runtime from the above two fields, although it will be slightly inefficient I guess to compute the value every time a task is added to the runqueue. If that is not desirable, then we can stick with option 1 (walk task list and change member task's->load_weight upon class limit change). -- Regards, vatsa - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
