Yep, makes sense. Let's do that, we can merge that branch into bpf-next/master and I will follow up with my changes on top of that. Let's just drop the do_one_ldimm64() extraction, and keep fdput(f) logic, plus add fd_file() accessor changes. I'll then add a switch to CLASS(fd) after a bit more BPF-specific clean ups. This code is pretty sensitive, so I'd rather have all the non-trivial refactoring done separately. Thanks!
