Re: [Xen-devel] simple backend, frontend

That one implements Xen's handling of event channel ops - you don't need to 
interact with it directly.

> linux-2.6.9-xen-sparse/drivers/xen/evtchn/evtchn.c or

That provides the event channel to userspace interaction - Xend uses it but 
you don't need to.

> linux-2.6.9-xen-sparse/arch/xen/kernel/evtchn.c

That's the one in kernel users will call into.

There's some magic that symlinks files from the 2.6 tree into the right place.  
I've never tried to figure out how it works, though ;-)
