I agree with Jens, makes a lot of sense to start with this feature
'off'.
To 'advertise' the feature, maybe make the feature a new selection in
Kconfig? Example, initially make it "EXPERIMENTAL", and later when
more devices implement this feature it can be integrated more tightly
into the NVMe solution and default to on.
Should we just leave the kernel out of this then? I bet we could script
this feature in user space.
