Subject: [PATCHv6 perf/core 13/22] selftests/bpf: Rename uprobe_syscall_executed prog to test_uretprobe_multi
Date: Sun, 20 Jul 2025 13:21:23 +0200 [thread overview]
Message-ID: <20250720112133.244369-14-jolsa@kernel.org> (raw)
In-Reply-To: <20250720112133.244369-1-jolsa@kernel.org>
Renaming uprobe_syscall_executed prog to test_uretprobe_multi
to fit properly in the following changes that add more programs.
Plus adding pid filter and increasing executed variable.
Acked-by: Andrii Nakryiko <andrii@kernel.org>
