Please do not put words in my mouth, that is not what I said.  I said
looking at Linux *code* should be avoided.  If you have a look at the
ATA *code*, you might copy their algorithms or whatever.  I am asking
you to be careful.  Looking at code might give you an idea about how
to solve a problem, you might even implement this and legally... well,
I am not sure when you violate copyright or when not.  I cannot tell
if you looked at their code if you opened the files, study the
variable names and how they are used.
