But if there's a possibility of more, an int model type that can be tested with a switch is more extensible. Personally I prefer bitfields over bool in structures, but ultimately Lorenzo will take this and I don't know whether he has a preference. https://lkml.kernel.org/r/CA+55aFxnePDimkVKVtv3gNmRGcwc8KQ5mHYvUxY8sAQg6yvVYg@xxxxxxxxxxxxxx https://lkml.kernel.org/r/CA+55aFzKQ6Pj18TB8p4Yr0M4t+S+BsiHH=BJNmn=76-NcjTj-g@xxxxxxxxxxxxxx Bjorn
