Jens Axboe e2d74ac066 [PATCH] [BLOCK] cfq-iosched: change cfq io context linking from list to tree ...

On setups with many disks, we spend a considerable amount of time
looking up the process-disk mapping on each queue of io. Testing with
a NULL based block driver, this costs 40-50% reduction in throughput
for 1000 disks.
