From 78becc27097585c6aec7043834cadde950ae79f2 Mon Sep 17 00:00:00 2001 From: Frederic Weisbecker Date: Fri, 12 Apr 2013 01:51:02 +0200 Subject: sched: Use an accessor to read the rq clock Read the runqueue clock through an accessor. This prepares for adding a debugging infrastructure to detect missing or redundant calls to update_rq_clock() between a scheduler's entry and exit point.
