Subject: [PATCH RFCv2 01/18] uprobes: Rename arch_uretprobe_trampoline function
Date: Mon, 24 Feb 2025 15:01:33 +0100 [thread overview]
Message-ID: <20250224140151.667679-2-jolsa@kernel.org> (raw)
In-Reply-To: <20250224140151.667679-1-jolsa@kernel.org>
We are about to add uprobe trampoline, so cleaning up the namespace.
Acked-by: Andrii Nakryiko <andrii@kernel.org>
