From 2a70b7879b84d471fd0e440f027bba310e0c1fb7 Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Thu, 12 Apr 2018 15:19:44 +0200 Subject: y2038: ipc: Use ktime_get_real_seconds consistently In some places, we still used get_seconds() instead of ktime_get_real_seconds(), and I'm changing the remaining ones now to all use ktime_get_real_seconds() so we use the full available range for timestamps instead of overflowing the 'unsigned long' return value in year 2106 on 32-bit kernels.
