Shin'ichiro, > SAT SCSI/ATA Translation specification requires SCSI SYNCHRONIZE CACHE > (10) and (16) commands both shall be translated to ATA flush command. > Also, ZBC Zoned Block Commands specification mandates SYNCHRONIZE > CACHE (16) command support.

To avoid the failure, add support for SYNCHRONIZE CACHE (16). Reviewed-by: Martin K. Petersen <martin.petersen@xxxxxxxxxx> -- Martin K. Petersen Oracle Linux Engineering
