Is it possible to code a loadable module having function1(), which
would be called, everytime a particular function of the kernel is
called? If not, atleast a way this could be done without re-compiling
the whole kernel and rebooting the system?

Example:

My LKM:
-------------

init_module() {
...
}

function1() {
...
}

cleanup_module() {
...
}


I want function1() to be called, everytime the function
ide_do_rw_disk() of ide-disk.c is called. I do not want to re-compile
the complete kernel to do this.

Thanks in advance,

Regards,
S
