selftests/bpf: Add attach bench test Adding test that reads all functions from ftrace available_filter_functions file and attach them all through kprobe_multi API. It also prints stats info with -v option, like on my setup: test_bench_attach: found 48712 functions test_bench_attach: attached in 1.069s test_bench_attach: detached in 0.373s Acked-by: Andrii Nakryiko <andrii@kernel.org> Signed-off-by: Jiri Olsa <jolsa@kernel.org> Link: https://lore.kernel.org/r/20220510122616.2652285-6-jolsa@kernel.org Signed-off-by: Alexei Starovoitov <ast@kernel.org> 2022-05-10 14:26:16 +02:00			`// SPDX-License-Identifier: GPL-2.0`
