From 44142fac3446d08c08c5d717ec11d50a737e8640 Mon Sep 17 00:00:00 2001 From: Ingo Molnar Date: Mon, 15 Oct 2007 17:00:01 +0200 Subject: sched: fix sysctl_sched_child_runs_first flag fix the sched_child_runs_first flag: always call into ->task_new() if we are on the same CPU, as SCHED_OTHER tasks depend on it for correct initial setup.
