From mboxrd@z Thu Jan 1 00:00:00 1970 Date: Thu, 10 Nov 2005 19:41:01 +0900 From: Yasunori Goto Subject: [Patch:RFC] New zone ZONE_EASY_RECLAIM[2/5] Message-Id: <20051110185812.0232.Y-GOTO@jp.fujitsu.com> MIME-Version: 1.0 Content-Type: text/plain; charset="US-ASCII" Content-Transfer-Encoding: 7bit Sender: owner-linux-mm@kvack.org Return-Path: To: linux-mm , Linux Hotplug Memory Support Cc: Nick Piggin , Mel Gorman List-ID: This defines new zone ZONE_EASY_RECLAIM. Note: I found DMA32_ZONE is included in -mm tree. If one more new zone is created before/after my patch, the zone number field in page->flags is not enough. My patch doesn't care about it yet.
