Comment 5 for bug 1817784

Sorry, I'm unable to verify this for xenial. I submitted it as an SRU back to 4.4 because it had already landed in the stable queue for 4.4, and is a trivial change[*]. I think we'd need a system that either uses mvsas or aix94xx to actually exercise this libsas code on 4.4.

I do have a system that uses the hisi_sas driver, which also uses libsas. That driver did not exist in 4.4. I gave backporting that driver a go, but it was coded w/ the pci_irq_vector API that came later.
