From e7f0d5cdd023d8fa53d9ca541b9a55f0eb45618c Mon Sep 17 00:00:00 2001 From: Changbin Du Date: Sun, 18 Dec 2022 06:35:09 +0800 Subject: bpf: makefiles: Do not generate empty vmlinux.h Remove the empty vmlinux.h if bpftool failed to dump btf info. The empty vmlinux.h can hide real error when reading output of make. This is done by adding .DELETE_ON_ERROR special target in related makefiles.
