Subject: [PATCH v4 bpf-next 3/4] tools/perf: Stop using bpf_object__find_program_by_title API.
Date: Mon, 13 Dec 2021 19:59:30 -0800	[thread overview]
Message-ID: <20211214035931.1148209-4-kuifeng@fb.com> (raw)
In-Reply-To: <20211214035931.1148209-1-kuifeng@fb.com>

bpf_obj__find_program_by_title() in libbpf is going to be deprecated.
Call bpf_object_for_each_program to find a program in the section with
a given name instead.
