I've saw said patches and performed local testing with a Rust-for-Linux
kernel, both in Qemu and bare metal, the kernel and it was working as
expected, bpftool could eject a proper header

$ bpftool btf dump file /sys/kernel/btf/vmlinux format c > vmlinux.h

and I could do BTF test from a guide by Aniket Bhattacharyea in
containiq.com (https://www.containiq.com/post/btf-bpf-type-format).

So yeah, I can say that this patch was effectively superseeded by the
patch series at next. Thanks for your attention though.
