From fb2426ad00b136c88d57457504d1e843159a367a Mon Sep 17 00:00:00 2001 From: Martin KaFai Lau Date: Wed, 15 Jan 2020 15:00:31 -0800 Subject: libbpf: Expose bpf_find_kernel_btf as a LIBBPF_API This patch exposes bpf_find_kernel_btf() as a LIBBPF_API. It will be used in 'bpftool map dump' in a following patch to dump a map with btf_vmlinux_value_type_id set. bpf_find_kernel_btf() is renamed to libbpf_find_kernel_btf() and moved to btf.c. As is included, some of the max/min type casting needs to be fixed.
