From d8dfe5bfe856c0c72b1750322dbfcad402e73373 Mon Sep 17 00:00:00 2001 From: Yonghong Song Date: Mon, 20 Jul 2020 09:33:59 -0700 Subject: [PATCH] tools/bpf: Sync btf_ids.h to tools Sync kernel header btf_ids.h to tools directory. Also define macro CONFIG_DEBUG_INFO_BTF before including btf_ids.h in prog_tests/resolve_btfids.c since non-stub definitions for BTF_ID_LIST etc. macros are defined under CONFIG_DEBUG_INFO_BTF. This prevented test_progs from failing.
