Subject: [PATCH bpf-next 3/6] tools: replace btf__get_from_id() with btf__load_from_kernel_by_id()
Date: Wed, 14 Jul 2021 15:15:29 +0100	[thread overview]
Message-ID: <20210714141532.28526-4-quentin@isovalent.com> (raw)
In-Reply-To: <20210714141532.28526-1-quentin@isovalent.com>

Replace the calls to deprecated function btf__get_from_id() with calls
to btf__load_from_kernel_by_id() in tools/ (bpftool, perf, selftests).
