I am not familiar with all the details here. Do you know a reason why
these cases would stop working / why special handling would be needed?
For example, if I have a UMEM that uses hugepages and XDP_PASS is
returned, then the data is just copied into an SKB right? SKBs can
also be created directly from hugepages AFAIK. So I don't understand
what the issue would be. Can someone explain this concern?
