It won't really be useful for you to send the failed hunk, because I
have no idea why it is failing.  I would suggest firing up a text editor
with fs/ext2/super.c and fs/ext2/super.c.rej and just manually cut-paste
the failed parts in.

Unified diffs are rather simple to understand.

Lines like "@@ -123,6 +234,8 @@" are telling you that the original file
had this hunk at line 123 and the modified file had the replacement
hunk at line 234.

Lines like "-                blah" are removing that line from the
original file and replacing it with "+           blarg" in the new file.

Hopefully hunk #10 isn't too large...  Sadly, the larger the hunk, the
more likely it is to not apply cleanly...

Cheers, Andreas
