architecture to implement communication between static kernel with dynamic module

architecture to implement communication between static kernel with dynamic module

[sounak chakraborty]

there is one my_own module
which i will insert whenever i like through 
insmod.
thus when the module is loaded it will create a proc
file 

now i want to send the structure variable of
task_struct
i.e p to the module from the kernel at point when the
execution passes
through forking a new process i.e 
at the function do_fork() in fork.c in linux/kernel
folder

how to do this

how can i call the module from that point  (i.e in
do_fork())
and pass the task_struct *p as parameter to the module

can i declare an arbitary name in fork.c of my module
and compile the new kernel?
i think i cannot since i am inserting a dynamic module
to a static kernel executable
and how does the kernel will know that this module
will be attached later to it.
it will show errors while compiling the new modified
kernel

can you help me ?
what path i must take
thanks 
sounak

Some kind of callback registration would do the job.

I think there are entirely too many module-wanabees on yahoo!

Can you tell us or me what it is that you are trying to do.
I don't want to know how you've coded it, but rather what
you are trying to accomplish even before you start to write
code!

If you tell us what it is that you are trying to accomplish,
then people who know something about the kernel may try
to teach you how do do it.

Also, it doesn't do any good to use another name from another
yahoo account. We all know that they are free and we can
detect when the same kinds of questions and answers are
repeated.
