Jens Axboe 26fed4ac4e block: flush plug based on hardware and software queue order ... We used to sort the plug list if we had multiple queues before dispatching requests to the IO scheduler. This usually isn't needed, but for certain workloads that interleave requests to disks, it's a less efficient to process the plug list one-by-one if everything is interleaved. Don't sort the list, but skip through it and flush out entries that have the same target at the same time.
