From 029632fbb7b7c9d85063cc9eb470de6c54873df3 Mon Sep 17 00:00:00 2001 From: Peter Zijlstra Date: Tue, 25 Oct 2011 10:00:11 +0200 Subject: sched: Make separate sched*.c translation units Since once needs to do something at conferences and fixing compile warnings doesn't actually require much if any attention I decided to break up the sched.c #include "*.c" fest. This further modularizes the scheduler code.
