From: Theodore Ts'o Subject: [PATCH 02/12] jbd2: revert "jbd2: add COW fields to struct jbd2_journal_handle" Date: Sat, 9 Feb 2013 16:53:42 -0500 Message-ID: <1360446832-12724-3-git-send-email-tytso@mit.edu> References: <1360446832-12724-1-git-send-email-tytso@mit.edu> Cc: Theodore Ts'o To: Ext4 Developers List Return-path: Received: from li9-11.members.linode.com ([67.18.176.11]:47599 "EHLO imap.thunk.org" rhost-flags-OK-OK-OK-OK) by vger.kernel.org with ESMTP id S1758694Ab3BIVxy (ORCPT ); Sat, 9 Feb 2013 16:53:54 -0500 In-Reply-To: <1360446832-12724-1-git-send-email-tytso@mit.edu> Sender: linux-ext4-owner@vger.kernel.org List-ID: This reverts commit 93737456d68ddcb86232f669b83da673dd12e351. The cow-snapshots effort is no longer active, so remove these extra fields to shrink down the handle structure.
