[PATCH v6 8/8] scsi: libsas: Update SATA dev FIS in sas_ata_task_done()
Posted by John Garry 3 years, 2 months ago
In sas_ata_task_done(), for commands which complete with error we set
the SATA dev FIS status field with ATA_ERR. In ata_eh_analyze_tf() this
would be interpreted as a HSM error. Set ATA_DRDY, which will lead libata
to judge as a device error, which is a safer bet.
