# HG changeset patch # User kaf24@xxxxxxxxxxxxxxxxxxxx # Node ID d265c79031afe9689271c03c56ed20069472f7ff # Parent 3d884434ec971b889621f42f442ec71b45349748 Just allocate unbound irq only from dynirq range, since pirq range is reserved for physical devices. This saves unnecessary checks on pirq range.
