Subject: [PATCH v2 bpf-next 09/11] selftests/bpf: switch BPF_ANNOTATE_KV_PAIR tests to BTF-defined maps
Date: Mon, 17 Jun 2019 12:26:58 -0700 [thread overview]
Message-ID: <20190617192700.2313445-10-andriin@fb.com> (raw)
In-Reply-To: <20190617192700.2313445-1-andriin@fb.com>
Switch tests that already rely on BTF to BTF-defined map definitions.
