Subject: [PATCH v9 4/6] x86/vdso: Use SYM_FUNC_{START,END} in __kernel_vsyscall()
Date: Wed, 11 Feb 2026 15:13:55 +0100 [thread overview]

In-Reply-To: <20260211141357.271402-1-jremus@linux.ibm.com>
From: Josh Poimboeuf <jpoimboe@kernel.org>
Use SYM_FUNC_{START,END} instead of all the boilerplate. No functional
change.
