No upstream review whatsoever ? That is pretty weak provenance. We
generally require SRU patches to have at least made it into linux-next.
The patches to infiniband core affect not only mlx5, but more then 10
other drivers. What testing has been performed for those ? (I suspect none).
This also looks like it should be split into 3 patches with a bit more
explanation for each.
