I went to /usr/src/linux/drivers/block/as-iosched.c line 1519, it's
located in this function, anyone know what arq is ?
static void
as_insert_request(request_queue_t *q, struct request *rq, int where)
{
struct as_data *ad = q->elevator->elevator_data;
struct as_rq *arq = RQ_DATA(rq);
if (arq) {
if (arq->state != AS_RQ_PRESCHED) {
printk("arq->state: %d\n", arq->state);
WARN_ON(1); <<======= line 1519
}
arq->state = AS_RQ_NEW;
}
/* barriers must flush the reorder queue */
if (unlikely(rq->flags & (REQ_SOFTBARRIER | REQ_HARDBARRIER)
&& where == ELEVATOR_INSERT_SORT)) {
WARN_ON(1);
where = ELEVATOR_INSERT_BACK;
}
switch (where) {
case ELEVATOR_INSERT_BACK:
while (ad->next_arq[REQ_SYNC])
as_move_to_dispatch(ad,
ad->next_arq[REQ_SYNC]);
while (ad->next_arq[REQ_ASYNC])
as_move_to_dispatch(ad,
ad->next_arq[REQ_ASYNC]);
list_add_tail(&rq->queuelist, ad->dispatch);
as_account_queued_request(ad, rq);
as_antic_stop(ad);
break;
case ELEVATOR_INSERT_FRONT:
list_add(&rq->queuelist, ad->dispatch);
as_account_queued_request(ad, rq);
as_antic_stop(ad);
break;
case ELEVATOR_INSERT_SORT:
BUG_ON(!blk_fs_request(rq));
as_add_request(ad, arq);
break;
default:
BUG();
return;
}
}
