Subject: [RFC perf/core 01/11] uprobes: Rename arch_uretprobe_trampoline function
Date: Tue,  5 Nov 2024 14:33:55 +0100	[thread overview]
Message-ID: <20241105133405.2703607-2-jolsa@kernel.org> (raw)
In-Reply-To: <20241105133405.2703607-1-jolsa@kernel.org>

We are about to add uprobe trampoline, so cleaning up the namespace.
