/* taka proba zasmiecenia dmesg-a przez wypisywanie ciagle "is usuing obsolete
 * setsockopt SO_BSDCOMPAT" :)  
 * ale jest to nie wypal bo kernel sie chroni sam bo w kernelu jest(net/sock/core.c):
 
static void sock_warn_obsolete_bsdism(const char *name)
{
        static int warned;
        static char warncomm[TASK_COMM_LEN];
        if (strcmp(warncomm, current->comm) && warned < 5) {
                strcpy(warncomm,  current->comm);
                printk(KERN_WARNING "process `%s' is using obsolete "
                       "%s SO_BSDCOMPAT\n", warncomm, name);
                warned++;
        }
}

 nie dziala bo jest "static int warned"
