That probably means that the SATA code uses the SCSI error > handler in another way than other SCSI LLDs. It's the ata_sas error handler, which is split between libsas and libata. It does one thread of execution per ata port when the strategy handler is invoked. This behaviour is pretty much unique at the moment.
