I was wondering if you could help me. I've recently resumed work on
the map of the Linux kernel - http://www.makelinux.net/kernel_map in
order to make it more up-to-date and to improve it. Please let me know
how I can update the map, as it would help me a lot.

Thank you in advance.
Constantine

A few quick comments:

1) Can we do better than an OSI 7-layer burrito? ;) As it stands, doing it
that way creates a lot of things that look like layering violations. For
instance, "Device Model" is up on "virtual", when it actually gets *used*
several levels further down. And you have a *lot* of vertical lines that
cross a whole bunch of levels. You would probably be served much better
by letting each column be a lot wider, and maybe only 4 levels high (you
can probably squish virtual/bridges/logical into one wider level).

1b) Much of the I/O column should be one wide section across the bottom of
disk/network/user peripherals, and the 'system run' box should be in some
other column(s).

2) Security and debugging seem to be forced in the "user peripherals" column
for no real rational reason.

3) I see no mention of tracing/oprofile/perf.

Hope that helps...
