sched: fix a find_busiest_group buglet
In one of the group load balancer patches:
commit 408ed066b11cf9ee4536573b4269ee3613bd735e
Author: Peter Zijlstra <a.p.zijlstra@chello.nl>
Date: Fri Jun 27 13:41:28 2008 +0200
Subject: sched: hierarchical load vs find_busiest_group
The following change:
- if (max_load - this_load + SCHED_LOAD_SCALE_FUZZ >=
+ if (max_load - this_load + 2*busiest_load_per_task >=
busiest_load_per_task * imbn) {
made the condition always true, because imbn is [1,2].
Therefore, remove the 2*, and give the it a fair chance.
