Subject: [PATCH bpf-next] bpftoo: Support user defined vmlinux path
Date: Mon, 25 Apr 2022 15:57:24 +0800 [thread overview]
Message-ID: <20220425075724.48540-1-jianlv@ebay.com> (raw)
From: Jianlin Lv <iecedge@gmail.com>
Add EXTERNAL_PATH variable that define unconventional vmlinux path
Signed-off-by: Jianlin Lv <iecedge@gmail.com>
