Date: Fri, 10 May 2013 16:40:13 -0700 From: "Darrick J. Wong" <darrick.wong@...cle.com> To: "Theodore Ts'o" <tytso@....edu> Cc: linux-kernel <linux-kernel@...r.kernel.org>, linux-ext4 <linux-ext4@...r.kernel.org>, linux-fsdevel <linux-fsdevel@...r.kernel.org> Subject: [PATCH] jbd2: Always set journal superblock checksum when writing out superblock Add a few missing calls to jbd2_superblock_csum_set just prior to calling jbd2_write_superblock. This fixes complaints about corrupt journals if metadata checksumming and journal checksumming are both enabled. Signed-off-by: Darrick J.
