        What we have right now is just the list of features that will be in
2.6. The code is going to changed a lot more than that o 2.4. Even some features
might get dropped, or might be buggy etc... Since we are actually commenting the
code and tracing the execution paths, it would be better to stick to 2.4 itself.

        Currently we are documenting the features which haven't been radically
modified (re-written, rmap can be considered as an addon ;-)). The Network layer
has been fairly stable, O(1) is also available on 2.4, which is what we are 
focusing on,
The VFS layer is also pretty much the same and so on... 

        There are new features and re-writes in 2.6 like the console layer, 
block layer etc..
but we are not covering them yet. Also the ETA for 2.6 is somewhere in late 
2003, so we got time
to cover as much of 2.4 code as possible.
