This approach somewhat reliable failed for me[1]. Also nothing else in
the kernel uses it. So I assume this is not really supported.

So this is the only solution, and the kernel usually uses _ as
delimiter for devices, so "xen_evtchn" is the name to use. And make
xen/evtchn a symlink for backward compatibility.
