Using modules to avoid the need of a reboot during development

[Andreas Fey]

Hi,

I want to add a custom routine to the tcp-code in the kernel 2.4.18.
Unfortunately I have to reboot the machine everytime I have made changes to
the kernel.
So my question is: Can I avoid the need of a reboot using a selfmade kernel
module ?

In tcp.c I want to call a dummy function. And when I insert the module it
should intercept the dummy function so that the code in the module is
executed instead of the function  in tcp.c. This would be great because all
the things I have to do is compiling and reinserting the module everytime I
have changed something in the code.

Can this be done in the 2.4 kernel ? Is this the right way to safe time
during kernel development or is there an easier way ?

Thank You, Andy.
