From mboxrd@z Thu Jan 1 00:00:00 1970 Date: Sat, 31 May 2003 12:14:48 -0700 From: William Lee Irwin III Subject: pgcl-2.5.70-bk5-2 Message-ID: <20030531191448.GA20413@holomorphy.com> Mime-Version: 1.0 Content-Type: text/plain; charset=us-ascii Content-Disposition: inline Sender: owner-linux-mm@kvack.org Return-Path: To: linux-kernel@vger.kernel.org Cc: linux-mm@kvack.org List-ID: This release corrects a showstopping list handling bug in the pgd slab management code. When PAGE_MMUCOUNT > 1, the pgd : struct page relation becomes N:1, so that pgd_ctor() and pgd_dtor() may be called multiple times for each page dedicated to the pgd slab. The bug was that pgd_ctor() did an unconditional list_add(&page->lru, &pgd_list) and pgd_dtor() did an unconditional list_del(&page->lru, &pgd_list) regardless of whether the page backing the pgd's passed as an argument was already on the pgd_list. There was also a bug in pageattr.c where the pieces of a pgd slab page weren't iterated over when looping over pgd slab pages. A minor highmem compilefix and a fixes for /proc/vmstat reporting inaccuracies are also included. pgcl-2.5.70-bk5-2 survives a couple of hours of running dbench and tiobench in a loop.
