This is a good set of questions. We have about half dozen files in /proc/xen right now. One is an obvious canididate to stick in /dev, as it has primarily an ioctl() interface. The remainder are static, are read-only or read-write with ascii text, and we don't want hotplug events and other baggage.

Maybe making these attributes of a Xen system device makes sense. Are there examples in the kernel of other subsystems/modules with a similar miscellaneous set of files?
