From dc567045f1590f6460d3e9a6ea6ad5e600b58b84 Mon Sep 17 00:00:00 2001 From: Xin Liu Date: Tue, 13 Sep 2022 15:36:43 +0800 Subject: [PATCH] libbpf: Clean up legacy bpf maps declaration in bpf_helpers Legacy BPF map declarations are no longer supported in libbpf v1.0 [0]. Only BTF-defined maps are supported starting from v1.0, so it is time to remove the definition of bpf_map_def in bpf_helpers.h.
