And then possibly # reconsider # the decisions you have recently made that caused you to write special # code to use that crazy thing. Personally, it still feels like a # solution in search of a problem. I agree with you that SGX is "crazy", but this makes no sense. SGX is expected to protect enclave even from root. How does making interface root-only solve that? Plus, SGX is not in 4.19. I don't believe it is in mainline, either, as the patches are still reposted. We are at v40 now...
