+Subject: [PATCH] Fix builds against bcc >= 0.25.0
+
+libbpf 1.0.0 removed bpf_load_program_attr in
+https://github.com/libbpf/libbpf/commit/9476dce6fe905a6bf1d4c483f7b2b8575c4ffb2d
+and bcc 0.25.0 in turn changed bcc_prog_load_xattr to use
+bpf_prog_load_opts instead in
+https://github.com/iovisor/bcc/commit/185143bdec6134255363446f644acd766ffb3825
+
+Add a compile check to use the appropriate version
