This is a nice idea, and I was thinking of writing something like this
for a while and couldn't do it for lack of time. However, don't under
estimate the effort in writing such a howto. It's pretty easy to write a
simple file system that can be mounted and has simple read/write
capability using generic functions. But, the devil is in the details. A
clear demonstration of usage of buffer cache and your own versions of
generic_file_read and generic_file_write is a tough task. I don't mean
to discourage you and please post a link to your doc to the list.
BTW, I am the author of the logfs for Linux
