We don't do max bandwidth control in the SCHED_OTHER bits as I oppose to making it non work conserving. SCHED_FIFO/RR do constant bandwidth things and are always scheduled in favour of SCHED_OTHER. That is, we provide a minimum bandwidth for real-time tasks, but since having a maximum higher than the minimum is useless since one cannot rely on it (non deterministic) we put max = min. -- dm-devel mailing list dm-devel@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/dm-devel
