My current understanding is that the skb, while being passed along various
layers in linux network stack, will be manipulated majorly, using the
skb-{head|data|tail|end|len} fields.
Suppose that my application (say 'ping') sends a ICMP echo request with a
large packet size of 4k, i.e. $ ping -s

Hello everyone,
I am interested in Linux kernel programming (and OS kernels and
general), and I am currently reading several books about Linux kernel. I
have a few questions about it:
1.) Currently, I am reading 2 books about Linux kernel: Linux Device

You might want to get yourself an up to date kernel, as the code
sorry for my outof date kernel .
In the zap_low_mappingd function.there is a selection for kernel,as below:
#ifdef CONFIG_X86_PAE
set_pgd(swapper_pg_dir+i, __pgd(1 + __pa(empty_zero_page)));
#else
set_pgd(swapper_pg_dir+i, __pgd(0));
#endif
