Subject: [PATCH 2/4] x86/um/vdso: Use prototypes from generic vDSO headers
Date: Mon, 13 Oct 2025 12:40:19 +0200 [thread overview]
Message-ID: <20251013-uml-vdso-cleanup-v1-2-a079c7adcc69@weissschuh.net> (raw)
In-Reply-To: <20251013-uml-vdso-cleanup-v1-0-a079c7adcc69@weissschuh.net>
The generic vDSO library provides a convenient header for the vDSO
function prototypes, use it.
