From bde9e963af2d0a9762781c4dccaef21696d5bb94 Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Fri, 20 Apr 2018 22:03:38 +0200 Subject: y2038: timerfd: Use timespec64 internally timerfd_show() uses a 'struct itimerspec' internally, but that is deprecated because of the time_t overflow and a conflict with the glibc type of the same name that is now incompatible in user space. Use a pair of timespec64 variables instead as a simple replacement. As this removes the last use of itimerspec from the kernel, allowing the removal of the definition from the uapi headers along with timespec and timeval later.
