With this patch, users can make use of the SANITIZE DEVICE feature
set through utility like sg_sanitize.
Support for BLOCK ERASE, CRYPTOGRAPHIC ERASE and EXIT FAILURE MODE

To be honest, that sounds like FUD to me.
The exact reason why this can "safely" be introduced to the SATL is
that, it is a "one-shot" command that would only be triggered by the
user through a user space utility. It's nothing like TRIM that would
be triggered by the filesystem layer or so "from t

I don't suppose there would be any problem doing it in userspace /
with ATA PASS-THROUGH anyway. I just couldn't agree that it would be
the reason not to implement the translation (which covers the core
part of the feature set) in the kernel. But certainly I wouldn't keep
aruging on this.
