From abcfb5d979892fc8b12574551fc907c05fe1b11b Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Thu, 30 Jun 2016 11:49:01 -0400 Subject: jbd2: make journal y2038 safe The jbd2 journal stores the commit time in 64-bit seconds and 32-bit nanoseconds, which avoids an overflow in 2038, but it gets the numbers from current_kernel_time(), which uses 'long' seconds on 32-bit architectures. This simply changes the code to call current_kernel_time64() so we use 64-bit seconds consistently.
