From f93e5436f0ee5a85eaa3a86d2614d215873fb18b Mon Sep 17 00:00:00 2001 From: "Darrick J. Wong" Date: Mon, 17 Aug 2020 09:59:07 -0700 Subject: xfs: widen ondisk inode timestamps to deal with y2038+ Redesign the ondisk inode timestamps to be a simple unsigned 64-bit counter of nanoseconds since 14 Dec 1901 (i.e. the minimum time in the 32-bit unix time epoch). This enables us to handle dates up to 2486, which solves the y2038 problem. Signed-off-by: Darrick J.
