Message-ID: <20080224144710.GD31293@lazybastard.org> Date: Sun, 24 Feb 2008 15:47:11 +0100 From: Jörn Engel <joern@...fs.org> To: linux-mm@...ck.org, linux-kernel@...r.kernel.org Subject: Page scan keeps touching kernel text pages While tracking down some unrelated bug I noticed that shrink_page_list() keeps testing very low page numbers (aka kernel text) until deciding that the page lacks a mapping and cannot get freed. Looks like a waste of cpu and cachelines to me. Is there a better reason for this behaviour than lack of a patch?
