Or the documentation is b0rken? This is how the load figure is actually
calculated:
/*
* Nr of active tasks - counted in fixed-point numbers
*/
static unsigned long count_active_tasks(void)
{
struct task_struct *p;
unsigned long nr = 0;
read_lock(&tasklist_lock);
for_each_task(p) {
if ((p->state == TASK_RUNNING ||
(p->state & TASK_UNINTERRUPTIBLE)))
nr += FIXED_1;
}
read_unlock(&tasklist_lock);
return nr;
}
