From 551f209164c4d2cb8d5542351f145e8257c44702 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Thomas=20Wei=C3=9Fschuh?= Date: Thu, 21 May 2026 08:53:16 +0200 Subject: [PATCH] vdso/datastore: Always provide symbol declarations MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Allow callers to easily reference these symbols in code that is built even when the generic datastore is disabled. As there are no good default no-op variants of these symbols, do not provide stubs but require users to have their own fallback handling using IS_ENABLED(CONFIG_HAVE_GENERIC_VDSO).
