I guess such behavior is not expected, because it's not right to put real-time requests and best-effort requests in the same queue. The attached patch fixes the problem by introducing additional *cfqq fields on cfqd, pointing to per-(class,priority) async queues. Signed-off-by: Jens Axboe --- Reading git-diff-tree failed
