    I think you need to talk to the stable maintainers not the iommu
    upstream folks. I don't well know their policy.

    Frankly, I'd suggest just proposing the necessary (and tested)
    upstream patches to 6.1, however large they are, and see what Greg and
    Sasha say. This is the usual working model they have, as I understand
    it.
