I don't see anything in this series using this new interface, why is it
added now?

Hi, Jakub.

This interface is needed by the roce client, whose patch will be
upstreamed to the rdma tree, it is other branch. So we provide this 
interface previously, then the rdma guy will upstream their patch later,
maybe linux-5.8-rc*.

Thanks.
