With the change to CRCs by default, the mkfs inode size is defaults to 512 bytes and the minimum block size changes to 1024 bytes. This causes mismatches with golden output that expects the inode size to be 256 bytes, and some tests are tailored around the amount of space inside a 256 byte inode. Fix them with appropriate filtering or mkfs parameters to allow 256 byte inodes to be used. Signed-off-by: Dave Chinner <dchinner@redhat.com> Signed-off-by: Dave Chinner <david@fromorbit.com>
