From a275254975a29c51929ee175b92ac471ac2a0043 Mon Sep 17 00:00:00 2001 From: john stultz Date: Mon, 26 Jun 2006 00:25:14 -0700 Subject: [PATCH] [PATCH] time: rename clocksource functions As suggested by Roman Zippel, change clocksource functions to use clocksource_xyz rather then xyz_clocksource to avoid polluting the namespace.
