From 0da39687a15403251bdfd1c6fb18025c0607326b Mon Sep 17 00:00:00 2001 From: Tina Ruchandani Date: Fri, 30 Oct 2015 01:30:40 -0700 Subject: stex: Remove use of struct timeval Function stex_gettime uses 'struct timeval' whose tv_sec value will overflow on 32-bit systems in year 2038 and beyond. This patch replaces the use of struct timeval and do_gettimeofday with ktime_get_real_seconds, which returns a 64-bit seconds value.
