cfq-iosched: rethink seeky detection for SSDs
CFQ currently applies the same logic of detecting seeky queues and grouping them together for rotational disks as well as SSDs. For SSDs, the time to complete a request doesn't depend on the request location, but only on the size. This patch therefore changes the criterion to group queues by request size in case of SSDs, in order to achieve better fairness. Signed-off-by: Corrado Zoccolo <> Signed-off-by: Jens Axboe <>
