Check for the function proc_net_create(...) for the netstat part.

netstat -na might be reading from some /proc file. You can just find out
the kernel module that registers for writing to that /proc file and
refer to the data structure that it traverses while writing to /proc.

I think u didn't get me. We r developing a kernel
module( we r working at network layer) n want to find
whether there r any open streams from kernel code
itself.
