I have gone through LDD3 page 31. But it didn't answer my question. It is describing module init and exit when manually loading driver and removing it.
I want to know when one of auxdriver (selected in from menuconfig) is built as built-in module. When and Who calls it's init function ?
Thanks,
Rahul

no difference in the use of the init function (it's called at kernel
startup, I suppose) but exit is simply discarded in this case, because if
your module is built-in, it could never be removed.
