Subject: [PATCH 54/54] mke2fs: Enable metadata_csum on ext4dev filesystems
Date: Tue, 06 Mar 2012 16:03:44 -0800 [thread overview]
Message-ID: <20120307000344.11945.47813.stgit@elm3b70.beaverton.ibm.com> (raw)
In-Reply-To: <20120306235720.11945.30629.stgit@elm3b70.beaverton.ibm.com>
Enable full-power metadata checksumming by default on 'ext4dev' filesystems.
This should be fairly safe for now, since only developers should be using this
new feature.
