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?
