From c766d1472c70d25ad475cf56042af1652e792b23 Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Thu, 20 Feb 2020 20:03:57 -0800 Subject: y2038: hide timeval/timespec/itimerval/itimerspec types There are no in-kernel users remaining, but there may still be users that include linux/time.h instead of sys/time.h from user space, so leave the types available to user space while hiding them from kernel space. Only the __kernel_old_* versions of these types remain now.
