Hi,

I begin to program in the kernel a year ago when I start LIDS project. At
that time, I do not have much acknoledge about the impletementation of the
linux kernel. I just read the source and program at the same time. At that
time, I get serveral books from my friends. 1) << linux kernel internal>>
2) <<Linux Device Programming>> 3) << linux kernel source commmentary>>.
and other BSD related books. 

The most importants things is pratising..;-) programming LIDS give me a
lot of real experiment with the kernel. But I still can not understand
some impletementation of the kernel, and I still looking into the source
to learn more about that.

I think we can learn from each other. 

Cheers,
XIE
