Hi Steve,

For your illumination, here's where I'm currently at with making cifs use
netfslib more fully.  I ended up delving into the realms of converting it
to use iov_iter instead of page lists and doing partial foliation.

It isn't complete yet and some of the patches don't compile, but if you
want a look at what I've been doing...

David
