Are you going to propose a Documentation/ABI/ patch to help with that? e.g., Documentation/ABI/testing/sysfs-platform-vhci-hcd? I'm frankly not that familiar with usbip (I'm just trying to help David out) and might not be the best person for describing the details exposed here. And are you planning to try something else to maintain compatibility pre-[1]? I'm not saying you have to, but you mentioned it and I'd like to know if we're doing any duplicate work.
