Bug description:
  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.
