Ran these overnight on 2 machines on top of recent BFQ and nothing caught on fire. One funny benchmark result stood out since it gave me (repeatedly!) 560 MB/s read bandwidth on an SSD which is rated to do "up to 550MB/s", so I guess BFQ's bandwidth guarantees are now really quite strong. :-)
Therefore: Tested-by: Holger Hoffstätte <holger@applied-asynchrony.com>
