Subject: ata: libata-scsi: fix SYNCHRONIZE CACHE (16) command failure
From: Shin'ichiro Kawasaki <shinichiro.kawasaki@xxxxxxx>
commit ea045fd344cb15c164e9ffc8b8cffb6883df8475 upstream.
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. However, libata translates only SYNCHRONIZE CACHE
(10). This results in SYNCHRONIZE CACHE (16) command failures on SATA
drives and then libata translation does not conform to ZBC. To avoid the
failure, add support for SYNCHRONIZE CACHE (16).
