If I and you are looking at the same patch, you're misreading the
patch.  From the patch description...

 I'm attaching a patch that fixes it. It basically follows
 http://linux-ata.org/shutdown.html and *SKIPS* the drive shutdown when
 the respective /sys/block/sdX/device/scsi_disk:*/manage_start_stop
 exists (leaving it for the kernel to do).
