Subject: [PATCH] bpf: fix: symbol 'btf_vmlinux' was not declared.
Date: Thu, 24 Dec 2020 16:00:48 +0800 [thread overview]
Message-ID: <1608796848-49865-1-git-send-email-abaci-bugfix@linux.alibaba.com> (raw)
Symbol 'btf_vmlinux' was not declared in the header file and does not
add extern, so no other file uses it. It's better to add static to it.
