I have written a few file servers under lib9p and lib9pfile,
I am now trying to write a kernel file server and just a little
unsure about the differences.
I think the major change writing for the kernel is I am responsible for
keeping the Path in the Chan up to date as the I get service
fscreate, fsclone (just bump refernce count), and fswalk.
I'am not sure how I should leave the Path of walk if the walk fails?
Anything else I need to do/provide?

the best way to approach this is to look
at a couple kernel file servers. #e is a
good example of a dynamic 1-level fs.
#r is a good example of a table-driven one.
