From a8802d97e73346bc81609df9dfba7d3306f40d87 Mon Sep 17 00:00:00 2001 From: Eric Dumazet Date: Wed, 11 Jul 2018 11:16:41 -0700 Subject: [PATCH] ktime: Provide typesafe ktime_to_ns() Using ktime_to_ns() is nice to help backports to stable kernels. Having a typesafe function instead of a macro avoid stupid typos and waste of time tracking these typos.
