Hi,
Could you please suggest ?how to freeze ?the 2.6 kernel(SMP m/c) with
my own dlkm with ?less number of code.
I tried the below mentioned code snippet, it hangs only the terminal
on which i executed the insmod command.
?Please correct the below code to freeze whole kernel.
#include <linux/module.h>
#include <linux/kernel.h>
#include <linux/spinlock.h>
#include <linux/delay.h>
int init_module(void)
{
? ? ? ?spinlock_t lock = SPIN_LOCK_UNLOCKED;
? ? ? ?while (1) {
? ? ? ? ? ? ? ?spin_lock(&lock);
? ? ? ? ? ? ? ?msleep(100);
? ? ? ? }
? ? ? ?//spin_unlock(lock);
? ? ? ?printk(KERN_INFO "Hello world :).\n");
? ? ? ?return 0;
