Re: new filesystem module

I'm working on kernel 2.2.26. I'm trying to add a new filesystem
module, this filesystem is mainly the ext2 one but i'd want to add
some new features, as the possibility to log file actions.
I have some questions.
What are the steps for adding a new filesystem?
how to clone ext2 filesystem and working on this copy easily ?

Depending on the details of what you're trying to do and why you're
trying to do it, using FUSE to create a logging filesystem is
straightforward (it's what I did as my first experiment learning how
to use FUSE), and has the bonus that it isn't tied to an underlying
filesystem design.
