Yes, I also like the file system, I guess this is 2.6.28 material and
you should have it added to linux-next when you have addressed the
comments so far.

One thing that would be really nice is if you could add fake-write
support in the way that I proposed for cramfs a few months ago.
This would make axfs much more interesting for another set of
users, and keep cramfs a really simple example file system.
