Message-ID: <5035E846.50707@jp.fujitsu.com> Date: Thu, 23 Aug 2012 17:22:30 +0900 From: Yasuaki Ishimatsu <isimatu.yasuaki@...fujitsu.com> To: Lai Jiangshan <laijs@...fujitsu.com> CC: Mel Gorman <mel@....ul.ie>, <linux-kernel@...r.kernel.org> Subject: Re: [RFC V3 PATCH 00/25] memory,numa: introduce MOVABLE-dedicated node and online_movable for hotplug Hi Lai, Sorry for late reply. I'm trying to apply your patchset into linux-3.6-rc3. But I failed to apply them. What is the based kernel that can apply your patch?
