Even with explicit FIFO, you're still gonna have similar problems as people crowd that flag. If this is a concern, please benchmark with realistic scenarios and consider other options (e.g. maybe that problematic workqueue doesn't need to be HIGHPRI or should be split somehow). Right now, I don't think there are enough justifications for adding another level. Thanks. -- tejun
