Subject: [PATCH] mempolicy:add GFP_THISNODE when allocing new page
Date: Tue, 6 Apr 2010 10:59:37 +0800 [thread overview]
Message-ID: <1270522777-9216-1-git-send-email-lliubbo@gmail.com> (raw)
In funtion migrate_pages(), if the dest node have no
enough free pages,it will fallback to other nodes.
Add GFP_THISNODE to avoid this, the same as what
funtion new_page_node() do in migrate.c.
