From mboxrd@z Thu Jan 1 00:00:00 1970 Date: Tue, 19 Feb 2002 11:34:15 -0300 (BRT) From: Rik van Riel Subject: [PATCH *] new struct page shrinkage Message-ID: MIME-Version: 1.0 Content-Type: TEXT/PLAIN; charset=US-ASCII Sender: owner-linux-mm@kvack.org Return-Path: To: Linus Torvalds Cc: linux-kernel@vger.kernel.org, linux-mm@kvack.org List-ID: Hi Linus, The patch has been changed like you wanted, with page->zone shoved into page->flags. I've also pulled the thing up to your latest changes from linux.bkbits.net so you should be able to just pull it into your tree from: bk://linuxvm.bkbits.net/linux-2.5-struct_page You can also view the patch on: http://surriel.com/patches/2.5/2.5.5-p2-struct_page5 I'm not retransmitting it to lkml as very little has changed. Please apply the patch to your 2.5 tree. thank you, Rik ----> begin standard blurb of explanation <---- I've forward-ported a small part of the -rmap patch to 2.5, the shrinkage of the struct page. Most of this code is from William Irwin and Christoph Hellwig. The executive summary: o page->wait is removed, instead we use a hash table of wait queues per zone ... collisions are ok because of wake-all semantics o page->virtual is only used on highmem machines and sparc64, other machines calculate the address instead o page->zone is moved into page->flags Linus, please pull from the bk tree: bk://linuxvm.bkbits.net/linux-2.5-struct_page -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@kvack.org.
