From 8b0e195314fabd58a331c4f7b6db75a1565535d7 Mon Sep 17 00:00:00 2001 From: Thomas Gleixner Date: Sun, 25 Dec 2016 12:30:41 +0100 Subject: ktime: Cleanup ktime_set() usage ktime_set(S,N) was required for the timespec storage type and is still useful for situations where a Seconds and Nanoseconds part of a time value needs to be converted. For anything where the Seconds argument is 0, this is pointless and can be replaced with a simple assignment.
