Irrelevant. The file system design has changed a *lot* since 2.0 (what is
described in the book, mostly). Look at the documentation bundled with the
latest 2.1 kernel you can get your hands on, check the filesystem sources
that are in there (particularly romfs (read-only, just one file; simplest
of the lot) and perhaps Minix (complete, but still simple)), check the
header files that are included by all carefully.

Then ask here. The guys that made all this happen hang out here, and might
be willing to answer intelligent questions.

Happy hacking!
