Subject: [PATCH bpf-next 01/13] uprobes: Rename arch_uretprobe_trampoline function
Date: Wed, 11 Dec 2024 14:33:50 +0100 [thread overview]
Message-ID: <20241211133403.208920-2-jolsa@kernel.org> (raw)
In-Reply-To: <20241211133403.208920-1-jolsa@kernel.org>
We are about to add uprobe trampoline, so cleaning up the namespace.
