I think it's pretty clear that page frag allocator was never supposed to support GFP_ZERO, as we don't need it in networking.. So maybe you're better off adding the memset() in nvme? CCing Alex, who I think would say something along those lines :) IDK how much we still care given that most networking drivers are migrating to page_poll these days.
