Subject: [PATCH 35/54] mke2fs: Record the checksum algorithm in use in the superblock
Date: Tue, 06 Mar 2012 16:01:29 -0800	[thread overview]
Message-ID: <20120307000129.11945.56042.stgit@elm3b70.beaverton.ibm.com> (raw)
In-Reply-To: <20120306235720.11945.30629.stgit@elm3b70.beaverton.ibm.com>

Record the type of checksum algorithm we're using for metadata in the
superblock when creating a filesystem.
