From 70845269b55dd275c19d253bbb79b36fbf9a83d6 Mon Sep 17 00:00:00 2001 From: Chris Redpath Date: Thu, 8 Aug 2013 16:10:39 +0100 Subject: [PATCH] sched: HMP change nr_running offload metric rq->nr_running was better than cfs.nr_running, since it includes all tasks actually on the CPU. However, it includes RT tasks which we would rather ignore at this point. Switching to cfs.h_nr_running includes all the CFS tasks but no RT tasks.
