From be80e9cdbca8ac66d09e0e24e0bd41d992362a0b Mon Sep 17 00:00:00 2001 From: Andrii Nakryiko Date: Wed, 3 Nov 2021 15:08:34 -0700 Subject: [PATCH] libbpf: Rename DECLARE_LIBBPF_OPTS into LIBBPF_OPTS It's confusing that libbpf-provided helper macro doesn't start with LIBBPF. Also "declare" vs "define" is confusing terminology, I can never remember and always have to look up previous examples. Bypass both issues by renaming DECLARE_LIBBPF_OPTS into a short and clean LIBBPF_OPTS. To avoid breaking existing code, provide: #define DECLARE_LIBBPF_OPTS LIBBPF_OPTS in libbpf_legacy.h. We can decide later if we ever want to remove it or we'll keep it forever because it doesn't add any maintainability burden.
