Subject: [patch v5 08/15] sched: move sg/sd_lb_stats struct ahead
Date: Mon, 18 Feb 2013 13:07:35 +0800	[thread overview]
Message-ID: <1361164062-20111-9-git-send-email-alex.shi@intel.com> (raw)
In-Reply-To: <1361164062-20111-1-git-send-email-alex.shi@intel.com>

Power aware fork/exec/wake balancing needs both of structs in incoming
patches. So move ahead before it.
