any help for the book "Kernel Project for Linux"?

[yan]

Now I'm studying this book.

I want to know if there are the keys for it.
I wrote some code for practise 1,and the c compiler gave me a warning,I do don't know how to get along with it under the condition that I don't own keys~
Any one can tell me where I can find the keys I need?

what kind of warning was it ? when compiling kernels at home i often get warning that come from slight variation between gcc distributions (for instance, the redhat-distributed GCC does not warn about comparing an unsigned to a signed int while SuSE-distributed one does).

for some reason yans 2 messages were cuasing some bizzare problems (failed to load from the DB!)..

every other messages is ok.. just yans two messages.
I have removed them..

i think it might have had something to do with offsite linking...

apologies here...
