Date: Tue, 14 Jan 2020 14:44:12 -0800 From: Martin KaFai Lau <kafai@...com> To: <bpf@...r.kernel.org> CC: Alexei Starovoitov <ast@...nel.org>, Daniel Borkmann <daniel@...earbox.net>, David Miller <davem@...emloft.net>, <kernel-team@...com>, <netdev@...r.kernel.org> Subject: [PATCH bpf-next 3/5] libbpf: Expose bpf_find_kernel_btf to libbpf_internal.h This patch exposes bpf_find_kernel_btf() to libbpf_internal.h. It will be used in 'bpftool map dump' in a following patch to dump a map with btf_vmlinux_value_type_id set.
