From mboxrd@z Thu Jan 1 00:00:00 1970 Date: Sun, 11 Nov 2007 09:45:56 +0100 From: Nick Piggin Subject: [patch 0/6] lockless pagecache Message-ID: <20071111084556.GC19816@wotan.suse.de> Mime-Version: 1.0 Content-Type: text/plain; charset=us-ascii Content-Disposition: inline Sender: owner-linux-mm@kvack.org Return-Path: To: Andrew Morton , Linus Torvalds , Peter Zijlstra , Hugh Dickins Cc: Linux Memory Management List List-ID: Hi, I wonder what everyone thinks about getting the lockless pagecache patch into -mm? This version uses Hugh's suggestion to avoid a smp_rmb and a load and branch in the lockless lookup side, and avoids some atomic ops in the reclaim path, and avoids using a page flag! The coolest thing about it is that it speeds up single-threaded pagecache lookups... Patches are against latest git for RFC. -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@kvack.org. For more info on Linux MM, see: http://www.linux-mm.org/ .
