Hello all,
can anyone give me a short hint how walking through the tasklist in a device
driver can be achieved nowadays. In ancient pre-20 times you could simply:
read_lock(&tasklist_lock);
p=current;
do {
if (p->pid==pid) {
read_unlock(&tasklist_lock);
/* found */
}
p=p->next_task;
} while (p!=current);
read_unlock(&tasklist_lock);
But since tasklist_lock is gone this is not safe any longer. So, what can I do?
