Hello,
 
so I built my driver with interrupt handling and got it compiled. When I
went to insmod I got an error from insmod saying:
 
Insmod: Unresolved Symbol wake_up_interruptable
Insmod: Unresolved Symbol interrptible_sleep_on_timeout

I have included the following header files:

#include <linux/interrupt.h>

#include <linux/delay.h>

#include <linux/string.h>

#include <linux/slab.h>

#include <linux/wait.h>

I think maybe I need to resolve dependencies in the kernel for these
symbols by adding the relevant driver or enabling the relevant feature
in the kernel configuration. But I am not sure which one it is.

Any idea's?
