Public bug reported:
[Impact]
Recent changes to the upstream driver improve write performance scalability
with large numbers of disks.
[Test Case]
Attach SSDs to the controller, and run fio with the attached configuration file
(adjust disk names as appropriate). You should see a nearly 2x improvement.
[Regression Risk]
The fixes are localized to the hisi_sas driver.
