The spec describes the sector size as

Over 4K will be fun.
And by "fun", you mean "irrelevant".
If anybody does that, they'll simply not work. And it's not worth it even
trying to handle it.
FSVO trying to handle...
At the driver level, it would be easy to clamp sector size to 4k, and
point the scatterlist to a zero-filled region for the >4k portion of
each sector. Inefficient, sure, but it is low-cost to the driver and
gives the user something other than a brick.

nvmhci_fill_sg_clamped_interleave()
else
nvmhci_fill_sg()
