We used to support syscalls in modules, but thankfully that is now gone.
But, how will this work for stuff like usbfs ioctls?  That is a module,
and our uapi is, by far, in drivers through ioctl "hell" and that would
be great to be able to document through all of this.  Will that just not
be in the debugfs api?
