From mboxrd@z Thu Jan 1 00:00:00 1970 Subject: [Fwd: Strange VM behavior on kernel 2.6.14.3] From: Marcelo Tosatti Content-Type: text/plain Date: Fri, 28 Apr 2006 17:08:10 -0300 Message-Id: <1146254890.4134.12.camel@dmt.cnet> Mime-Version: 1.0 Content-Transfer-Encoding: 7bit Sender: owner-linux-mm@kvack.org Return-Path: To: linux-mm@kvack.org, vito@hostway.com, akpm@osdl.org List-ID: Vito, There have been some changes after 2.6.14 in the reclaim code which might affect the problem you're seeing wrt large chunks of pagecache being freed. Folks, any ideas on what might be causing this? Please refer to document at the URL below, it contains quite some information. ----- Perhaps you can point me at a patch or some kind of information to help resolve/understand this problem, I have published some graphs and other data explaining the problem here on the web: http://shells.gnugeneration.com/~swivel/pop_comparisons/04-26-2006/ I might give the latest 2.6 kernel off kernel.org a try, as it looks like there has been some serious activity in the vm code lately... Except this is in production and I'd rather not fix one bug while potentially adding a handful of new ones... a patch fixing this specific problem on our kernel would be ideal.
