From cd29fe6f2637cc2ccbda5ac65f5332d6bf5fa3c6 Mon Sep 17 00:00:00 2001 From: Peter Zijlstra Date: Fri, 27 Nov 2009 17:32:46 +0100 Subject: sched: Sanitize fork() handling Currently we try to do task placement in wake_up_new_task() after we do the load-balance pass in sched_fork(). This yields complicated semantics in that we have to deal with tasks on different RQs and the set_task_cpu() calls in copy_process() and sched_fork() Rename ->task_new() to ->task_fork() and call it from sched_fork() before the balancing, this gives the policy a clear point to place the task.
