From 21346564ccad17b928cf0d51584608531d91d298 Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Tue, 5 Nov 2019 11:10:01 +0100 Subject: y2038: vdso: change time_t to __kernel_old_time_t Only x86 uses the 'time' syscall in vdso, so change that to __kernel_old_time_t as a preparation for removing 'time_t' and '__kernel_time_t' later.
