It doesn't apply to SAS devices.
If there is ATA/SATA temperature detection support in the kernel, it
should IMO also be mapped to SCSI/SAS commands as suggested by SAT (see
also the mail from Douglas Gilbert):
If SCSI Temperature Log page is requested (SCSI LOG SENSE cmd) for an
ATA/SATA device, read SMART attributes and return a Log page with
Temperature field set from attribute 194.
Does your patch support this?
SAT requires "SCT Status" or "Device Statistics" access method for
temperature. In practice, SMART attribute 194 is supported by much more
