Subject: Re: [PATCH] sched: Call update_group_power only for local_group
Date: Fri, 2 Jul 2010 09:56:39 -0700 [thread overview]
Message-ID: <1278089799-11949-1-git-send-email-venki@google.com> (raw)
In-Reply-To: <1278088816.1917.279.camel@laptop>
My fault. I completely missed that code path, assuming this_cpu in
load_balance means this_cpu :(
How about the change below instead?
