From 868bdd798190a689ddebf1fff7c41509e73c7cc0 Mon Sep 17 00:00:00 2001 From: "Jason A. Donenfeld" Date: Wed, 12 Jun 2019 15:05:50 +0200 Subject: global: switch to coarse ktime Coarse ktime is broken until [1] in 5.2 and kernels without the backport, so we use fallback code there. The fallback code has also been improved significantly. It now only uses slower clocks on kernels < 3.17, at the expense of some accuracy we're not overly concerned about.
