+Subject: [PATCH] Add a new switch to control whether udev complies with the
+ new SAT standards
+
+Reason: Original revisions of the SAT (SCSI-ATA Translation) specification,
+ udev will identify devices starting with 70 and ending with 00 1d as ATA devices,
+ rather than scsi devices, which may have a change in wwn id and affect user usage.
+ So Add a new switch to control whether udev complies with the new SAT standards
