Subject: [PATCHv3 bpf-next 21/26] selftests/bpf: Add uprobe_multi bench test
Date: Fri, 30 Jun 2023 10:33:39 +0200 [thread overview]
Message-ID: <20230630083344.984305-22-jolsa@kernel.org> (raw)
In-Reply-To: <20230630083344.984305-1-jolsa@kernel.org>
Adding test that attaches 50k uprobes in uprobe_multi binary.
After the attach is done we run the binary and make sure we
get proper amount of hits.
Signed-off-by: Jiri Olsa <jolsa@kernel.org>
