Hi Luis,

Todd doesn't have FSF copyright assignment so he shouldn't be on the ChangeLog.

Since Todd doesn't have copyright assignment these changes are
contributed to the FSF by IBM without author/contributor attribution.

You can simply attribute the changes to him in the email leaving his
name out of the sources per FSF policy and submit them on IBM's
behalf.
