Zdravim,

  pred nedavnem jsem kamaradovi napsal modulek, ktery mu zvedne uptime
(mozna nejjednodussi pouziti jiffies :-) )

[pouziti: gcc -O3 -c uptime.c; insmod uptime.o]
--------------------------X8------------------------------
#define MODULE
#define __KERNEL__

#include <linux/kernel.h>
#include <linux/module.h>
#include <linux/sched.h>                                                        
#include <linux/version.h> 

// Vyjedeme s uptime o 7 dni:

#define DNU    7
#define HODIN  0


#define NOVY 8640000 * DNU + 360000 * HODIN

int init_module(void) {
  printk("Uptime: %d ->%d\n",jiffies,jiffies+=NOVY);
  printk("Uptime zvednut o 7 dnu -- ");
  return 1;
}

void cleanup_module(void) {}
