The number of instances of common coupling between a module M and the other modules can be changed without any explicit change to M; this is termed "clandestine common coupling." This paper presents results from a study of clandestine common coupling in 391 versions of Linux. Specifically, the common coupling between each of 5332 kernel modules and the rest of the product as a whole was measured. In more than half of the new versions, a change in common coupling was observed, even though none of the modules themselves was changed.
