This patch set adds ability to auto-generate list of BPF helper definitions. It relies on existing scripts/bpf_helpers_doc.py and include/uapi/linux/bpf.h having a well-defined set of comments. All this is integrated with libbpf's Makefile to ensure that bpf_helpers_defs.h stays in sync with latest kernel UAPI. By checking bpf_helpers_defs.h, we also make sure that Github projection doesn't rely on latest kernel headers for successful build.
