From mboxrd@z Thu Jan 1 00:00:00 1970 From: Nick Piggin Message-Id: <20070210001844.21921.48605.sendpatchset@linux.site> Subject: [patch 0/3] 2.6.20 fix for PageUptodate memorder problem (try 3) Date: Sat, 10 Feb 2007 03:31:22 +0100 (CET) Sender: owner-linux-mm@kvack.org Return-Path: To: Andrew Morton Cc: Hugh Dickins , Nick Piggin , Linux Memory Management , Martin Schwidefsky , Linux Kernel List-ID: OK, I have got rid of SetPageUptodate_nowarn, and removed the atomic op from SetNewPageUptodate. Made PageUptodate_NoLock only issue the memory barrier is the page was uptodate (hopefully the compiler can thread the branch into the caller's branch). SetNewPageUptodate does not do the S390 page_test_and_clear_dirty, so I'd like to make sure that's OK. Rearranged the patch series so we don't have the first patch introducing a lot of WARN_ONs that are solved in the next two patches (rather, solve those issues first).
