Sorry. My patches were corrupted because my poor mailer had
removed spaces in the patch.
I will take care of it when I update this patch.

create ext2/3 which has more than 2**31-1 blocks.
It is because of the compatibility.

You should specify -j option to create ext3 as below.

# ./mke2fs -j /dev/md0
