Yes, it should be in the list archive somewhere, if you do a clean
unmount and use a recent xfs_db to relocate the log then you can run
xfs_repair to zero it before the first mount. You can ignore the
endian flipping stuff in the email if you have a recent xfs_db.
Note that this procedure does not fix up the backup superblocks
and if you ever need to recover the filesystem from these you may
run into problems.
