Since this patch necessitates a careful manual rebase of_every_ patch
in my series, I've included it at the top of my v2 submission and
rebased everything on top:
https://lkml.kernel.org/r/20210112110647.627783-1-a.darwish@xxxxxxxxxxxxx
Some left-over 'sas_ha' local variables were removed, and I've mentioned
that in the commit log of course.
