From 84ecc1f98ca7ce28ede9bc5cc70a557fdfa09caa Mon Sep 17 00:00:00 2001 From: Martin KaFai Lau Date: Wed, 5 Dec 2018 17:35:47 -0800 Subject: bpf: Expect !info.func_info and insn_off name changes in test_btf/libbpf/bpftool Similar to info.jited_*, info.func_info could be 0 if bpf_dump_raw_ok() == false. This patch makes changes to test_btf and bpftool to expect info.func_info could be 0. This patch also makes the needed changes for s/insn_offset/insn_off/.
