It's not the right way, it only solves a little part of the problem.
Killing a request with an error usually looks like this:
blkdev_dequeue_request(rq);
end_that_request_first(rq, 0, rq->hard_nr_sectors);
end_that_request_last(rq);
How do I get the request? do_ide_request() only get the complete
request_queue_t *q. Shell I use elv_next_request() ?
Yes.
So my workaround for now would be
--- linux-2.6.13-rc5/drivers/ide/ide-io.c
+++ linux-2.6.13-rc4-at91-multiIO/drivers/ide/ide-io.c
