Yes, I am part of BPF community, and also part of
LLVM community as I maintain the clang/llvm BPF backend with
Alexei Starovoitov.

I am a software engineer from Meta (former Facebook). I am in
the linux kernel team. Supporting the bpf community is part of my job,
which benefits Meta too.

No problem! If the community has any questions regarding to
BPF/BTF support in clang/llvm, they can reach me, Alexei, or
bpf mailing list and we are glad to help.
