Having a "root" directory for a single random driver seems like you are making your driver a "very important" thing in the overall scheme of the kernel, right? What's wrong with using the usb subdirectory like all other USB drivers use (after this patch series is merged)? That feels like a much more "sane" way to handle the wide-open debugfs namespace. Yes, there are no rules when it comes to debugfs file names and locations, but let's try to be sane please. thanks, greg k-h
