building custom module on 2.6.28 fails

[Satish Eerpini <eerpini@gmail.com>]

Hi everyone,

I tried to compile build the following sample kernel module on 2.6.28 :

______________________________________________________________________
#include <linux/module.h>
/* Defines the license for this LKM */
MODULE_LICENSE("GPL");
/* Init function called on module entry */

int my_module_init( void )
{
  printk(KERN_INFO "my_module_init called.  Module is now loaded.\n");
  return 0;
}

/* Cleanup function called on module exit */
void my_module_cleanup( void )
{
  printk(KERN_INFO "my_module_cleanup called.  Module is now unloaded.\n");
  return;
}

/* Declare entry and exit functions */
module_init( my_module_init );
module_exit( my_module_cleanup );
____________________________________________________________________

but it fails with the following error :

_____________________________________________________________________
