From 8182503df1baa077d1504cd192753b23530eb03c Mon Sep 17 00:00:00 2001 From: Shraddha Barke Date: Tue, 22 Dec 2015 14:02:19 +0530 Subject: [PATCH] block: sx8.c: Replace timeval with ktime_t 32-bit systems using 'struct timeval' will break in the year 2038, in order to avoid that replace the code with more appropriate types. This patch replaces timeval with 64 bit ktime_t which is y2038 safe. Since st->timestamp is only interested in seconds, directly using time64_t here. Function ktime_get_seconds is used since it uses monotonic instead of real time and thus will not cause overflow.
