From fac02ddf910814c24f5d9d969dfdab5227f6f3eb Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Fri, 13 Jul 2018 22:18:37 +0200 Subject: libceph: use timespec64 for r_mtime The request mtime field is used all over ceph, and is currently represented as a 'timespec' structure in Linux. This changes it to timespec64 to allow times beyond 2038, modifying all users at the same time.
