From 87d8b9eb7eb6669aad6435a51e9862362141ba76 Mon Sep 17 00:00:00 2001 From: Stephen Boyd Date: Thu, 18 Jul 2013 16:21:14 -0700 Subject: clocksource: Extract max nsec calculation into separate function We need to calculate the same number in the clocksource code and the sched_clock code, so extract this code into its own function. We also drop the min_t and just use min() because the two types are the same.
