Not exactly a libsas expert. James? Dan?
we have historically avoided this conflict because
ATA_PFLAG_SCSI_HOTPLUG is never set for libsas ata_ports. So the bug
/ behavior change is that ATA_PFLAG_SCSI_HOTPLUG gets set in the
first place. Ignoring it is a band-aid / not the real fix afaics.
where that flag is getting set?
