From b205656daf932c06aff424de5d6d01faf60faa5b Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Thomas=20Wei=C3=9Fschuh?= Date: Tue, 23 Dec 2025 07:59:12 +0100 Subject: [PATCH] vdso: Add prototype for __vdso_clock_getres_time64() MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit For consistency with __vdso_clock_gettime64() there should also be a 64-bit variant of clock_getres(). This will allow the extension of CONFIG_COMPAT_32BIT_TIME to the vDSO and finally the removal of 32-bit time types from the kernel and UAPI. The generic vDSO library already provides nearly all necessary building blocks for architectures to provide this function. Only a prototype is missing. Add the prototype to the generic header so architectures can start providing this function.
