Fix bug #12410 : InnoDB was too permissive with LOCK TABLE ... READ LOCAL, and alowed new inserts to the table; we now make READ LOCAL equivalent to READ for InnoDB; note that this will cause slightly more locking in mysqldump, but makes the InnoDB table dumps consistent with MyISAM table dumps; note that the real code change patch was accidentally pushed with my another patch 5 minutes ago
