Can you reference a specific commit, or point in time during 2013?
Looking at the git log quickly, if I go back to commit d726d8d719b6
("integrity: move integrity_audit_msg()") from March 18, 2013 (the
commit that created integrity_audit.c) the field ordering appears to
be the same as it today.

My NACK still stands.
