Subject: [PATCH RFCv3 01/23] uprobes: Rename arch_uretprobe_trampoline function
Date: Thu, 20 Mar 2025 12:41:36 +0100 [thread overview]
Message-ID: <20250320114200.14377-2-jolsa@kernel.org> (raw)
In-Reply-To: <20250320114200.14377-1-jolsa@kernel.org>
We are about to add uprobe trampoline, so cleaning up the namespace.
Acked-by: Andrii Nakryiko <andrii@kernel.org>
