well, all we do is:

1) have a common init and de-init function
2) call it from a wrapper funcion declared as module_init()
3) call it from a wrapper function declared __exit as module_exit()

Since 1) is called from init and fini, we cannot declare it as __init
(this would remove it from ram).

So what really happens is: calls from init to 'core' functions and calls
from 'exit' to core functions.
