From: Anatol Pomozov Subject: [PATCH 1/2] ext4: Realign trace events structs to make it smaller Date: Wed, 18 Jul 2012 10:07:33 -0700 Message-ID: <1342631254-23891-1-git-send-email-anatol.pomozov@gmail.com> Cc: adilger.kernel@dilger.ca, linux-ext4@vger.kernel.org, Anatol Pomozov To: tytso@mit.edu Return-path: Received: from mail-we0-f202.google.com ([74.125.82.202]:51696 "EHLO mail-we0-f202.google.com" rhost-flags-OK-OK-OK-OK) by vger.kernel.org with ESMTP id S1751281Ab2GRRHq (ORCPT ); Wed, 18 Jul 2012 13:07:46 -0400 Received: by weyr1 with SMTP id r1so100896wey.1 for ; Wed, 18 Jul 2012 10:07:44 -0700 (PDT) Sender: linux-ext4-owner@vger.kernel.org List-ID: Most hardware architectures require that data (including struct fields) have to be aligned in memory. To make it happen compiler inserts padding between struct fields if they are not aligned correctly. Reorder fields to remove paddings and make structures denser. Making data smaller saves some memory that is very important for trace events. Tracing buffer has limited size and making objects smaller we can put more of them without overflowing the tracing buffer. To find data struct holes I used 'pahole -H 1 -E -I vmlinux.o' from 'dwarves' package.
