Subject: [PATCHv6 perf/core 02/22] uprobes: Rename arch_uretprobe_trampoline function
Date: Sun, 20 Jul 2025 13:21:12 +0200 [thread overview]
Message-ID: <20250720112133.244369-3-jolsa@kernel.org> (raw)
In-Reply-To: <20250720112133.244369-1-jolsa@kernel.org>
We are about to add uprobe trampoline, so cleaning up the namespace.
