Patches 5 and 6 help simplify some tricky race avoidance code at the cost of possibly a very minor performance hit in page reclaim on some architectures. If they need any more justification they will be needed for lockless pagecache. Do these look OK? Thanks, Nick From mboxrd@z Thu Jan 1 00:00:00 1970 From: Nick Piggin Message-Id: <20060119192131.11913.27564.sendpatchset@linux.site> Subject: [patch 0/6] mm: optimisations and page ref simplifications Date: Thu, 19 Jan 2006 20:22:42 +0100 (CET) Sender: owner-linux-mm@kvack.org Return-Path: To: Linus Torvalds , Andrew Morton Cc: Nick Piggin , Linux Memory Management , Linux Kernel Mailing List List-ID: In the following patchset (against 2.6.16-rc1-git2), patches 1-4 reduce the number of locks and atomic operations required in some critical page manipulation paths.
