What are the benefits of the irqoff version? As far as I see it, the only use case for that function is when the caller has _explicitly_ disabled interrupts. The plain napi_schedule call will check if irqs are disabled. If they are, it won't do anything further in that area. There is no performance impact except for a check. > Needed is a function that dynamically picks the right version. So you want to replace a check with another check, am I right? How will that improve anything performance-wise?
