From mboxrd@z Thu Jan 1 00:00:00 1970 From: Wu Fengguang Subject: [PATCH 0/3] reduce readahead overheads on tmpfs mmap page faults v2 Date: Sat, 30 Apr 2011 11:22:43 +0800 Message-ID: <20110430032243.355805181__314.839572138403$1304134346$gmane$org@intel.com> Return-path: Sender: linux-kernel-owner@vger.kernel.org To: Andrew Morton , Andi Kleen Cc: Tim Chen , Li Shaohua , Wu Fengguang , LKML , Linux Memory Management List List-Id: linux-mm.kvack.org Andrew, I would like to update the changelogs for patches 2 and 3. There are no changes to the code. Sorry for the inconvenience. The original changelog is not accurate: it's solely the ra->mmap_miss updates that caused cache line bouncing on tmpfs. ra->prev_pos won't be updated at all on tmpfs. Thanks, Fengguang
