The quilt patch titled Subject: time_namespace: always provide arch_get_vdso_data() prototype for vdso has been removed from the -mm tree. Its filename was time_namespace-always-provide-arch_get_vdso_data-prototype-for-vdso.patch This patch was dropped because it was merged into the mm-nonmm-stable branch of git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm ------------------------------------------------------ From: Arnd Bergmann <arnd@xxxxxxxx> Subject: time_namespace: always provide arch_get_vdso_data() prototype for vdso Date: Wed, 17 May 2023 15:11:02 +0200 The arch_get_vdso_data() function is defined separately on each architecture, but only called when CONFIG_TIME_NS is set. If the definition is a global function, this causes a W=1 warning without TIME_NS: arch/x86/entry/vdso/vma.c:35:19: error: no previous prototype for 'arch_get_vdso_data' [-Werror=missing-prototypes] Move the prototype out of the #ifdef block to reliably turn off that warning.
