From 7c71feb0a6766c7c3a262e3cc33ae231f3953cb6 Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Fri, 17 Jun 2016 17:30:47 +0200 Subject: timer: Avoid using timespec The tstats_show() function prints a ktime_t variable by converting it to struct timespec first. The algorithm is ok, but we want to stop using timespec in general because of the 32-bit time_t overflow problem. This changes the code to use struct timespec64, without any functional change.
