From 3289bdb429884c0279bf9ab72dff7b934f19dfc6 Mon Sep 17 00:00:00 2001 From: Peter Zijlstra Date: Tue, 14 Apr 2015 13:19:42 +0200 Subject: sched: Move the loadavg code to a more obvious location I could not find the loadavg code.. turns out it was hidden in a file called proc.c. It further got mingled up with the cruft per rq load indexes (which we really want to get rid of). Move the per rq load indexes into the fair.c load-balance code (that's the only thing that uses them) and rename proc.c to loadavg.c so we can find it again.
