> For most other classes of hardware device driver framework KPIs -- especially things like PCI bus attachment, busdma, CAM, ifnet, and GEOM frameworks, our MFC rules would strictly disallow this sort of change, on the grounds that it is our KBI policy that we not break common classes of third-party device drivers (i.e., require them to be recompiled). My suspicion is that we should be applying the same rules to the USB framework -- however, I don't know if we have any third-party USB device drivers?
