(define ZONE_EASY_RECLAIM)[2/8] Message-Id: <20051220172750.1B0A.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 Kernel ML , linux-mm , Linux Hotplug Memory Support Cc: Joel Schopp List-ID: This defines new zone ZONE_EASY_RECLAIM. ZONES_SHIFT becomes 3. And this patch add member of sysctl_lowmem_reserve_ratio[]. take3 -> take 4: fixed number of index of sysctl_lowmem_reserve_ratio[]. take 2 -> take 3: add sysctl_lowmem_reserve_ratio[].
