Here is the summary with links:
- [v2,bpf-next,1/4] bpf: simplify btf_get_prog_ctx_type() into btf_is_prog_ctx_type()
https://git.kernel.org/bpf/bpf-next/c/fb5b86cfd4ef
- [v2,bpf-next,2/4] bpf: handle bpf_user_pt_regs_t typedef explicitly for PTR_TO_CTX global arg

- [v2,bpf-next,3/4] bpf: don't infer PTR_TO_CTX for programs with unnamed context type

You are awesome, thank you!
