ront_driver.c on the front end and xen_9pif.c on
the backend.
I am attaching an updated version of a writeup I made this summer.
It's table of contents is:
1. The state of the project
2. The approach I took
3. How to build my project
4. How to use it.

with Linda, I understood that h

much about how it is made to work? I ask because I'm a bit confused by
the notion of "virtio/9pfs" because what Linda did wasn't based on
virtio transport.
A clarification: If you mean the virtio 9pfs transport, my code is
based
a few existing Qemu files. The initialization is currently
done manually by modifying xenstore. This is the only code that
properly belongs in the hypervisor.
I hope this clarifies things.

In Linux the place to look is the various "otherend_changed" hooks in
the front and back drivers, usually the backend half is in a xenbus.c
file (e.g. netback and blkback).
