It could be.
Both ATA_12 and ATA_16 are just ways of getting a taskfile sent
down to the LLD, and ATA_12 is merely a re

Ahh.. my apologies on that, James.
The two patches apply and build independently,
and the second patch was only for libata, so it

I don't think I quite understand what you're trying to do here. My
understanding is that ATA_12 and ATA_16 are part of the SAT layer. i.e.
they're used when we're speaking SCSI to an underlying ATA device to
send taskfiles. However, ATAPI devices don't use SAT ... ever

In an ideal world, we would use the existing ATA_12 opcode
to issue 12-byte ATA passthrough commands for libata ATAPI drives
from userspace.
But ATA_12 happens to have the same SCSI opcode value as the older
CD/RW "BLANK" command, widely used by cdrecord and friends.
So, to achieve ATA passthru c
