Subject: [PATCH 0/2] sched: Idle load balance fixes
Date: Mon, 28 Apr 2014 15:45:53 -0700	[thread overview]
Message-ID: <1398725155-7591-1-git-send-email-jason.low2@hp.com> (raw)

[Resending to LKML]

This patchset includes fixes relating to idle_balance() and
rebalance_domains(). These apply on top of the following patches:

https://lkml.org/lkml/2014/4/23/767
https://lkml.org/lkml/2014/4/23/764

Patch #1 addresses an issue introduced by commit e5fc6611 which potentially
can cause rq->max_idle_balance_cost and rq->next_balance to not get updated
when it should.

Patch #2 fixes how rq->next_balance gets updated in idle_balance() and
rebalance_domains().

Jason Low (2):
  sched: Fix updating rq->max_idle_balance_cost and rq->next_balance in
    idle_balance()
  sched: Fix next_balance logic in rebalance_domains() and
    idle_balance()
