source changes without kernel re-compiling

source changes without kernel re-compiling

[sai narasimhamurthy]

Hi , 
I am working with the Linux networking source code for
the first time. 
I am working with the file tcp.c in
/usr/src/linux/net/ipv4 . Everytime I make a small
change, I recompile the kernel. Is there any way to
get the changes in tcp.c (or any file in /ipv4 , for
that matter) reflected without kernel re-compiling, so
that it saves time?
Sai

You modify the source, then you return to the top-level
directory and execute `make bzImage` or `make modules`
if you are modifying a module. Only the file(s) that
you modify will get compiled. The final link, of course,
gets done. But that's only a second or two.

is it possible to avoid even system reboots? 
(someway to make ordinary source files like tcp.c work
like modules, that is)
thanks,
Sai
