Hi all,
this series fixes the ATAPI DMA drain refactoring for SAS HBAs that
use libsas.
.
Something I meant to ask before and was curious about, specifically since
ipr doesn't actually use libsas: Why not wire up other SAS HBAs, like
megaraid_sas?
megaraid_sas and mpt3sas don't use the libata code at all. ipr actually
is a special case and uses libata directly instead of libsas (something
I hadn't realized, but which doesn't change anything for the patches
itself, just possibly the commit log).
More to the point, megaraid_sas and mpt3sas have their own SATL in
firmware so there is no need to use libata here.
Cheers,
Hannes
