Groklaw: Coupling and the Maintainability of the Linux Kernel

“A recently presented paper has the following abstract,
something that would certainly gain the attention of anyone
interested in Linux kernel development:

“Categorization of Common Coupling and Its Application
to the Maintainability of the Linux Kernel

“Data coupling between modules, especially common coupling, has
long been considered a source of concern in software design, but
the issue is somewhat more complicated for products that are
comprised of kernel modules together with optional nonkernel
modules. This paper presents a refined categorization of common
coupling based on definitions and uses between kernel and nonkernel
modules and applies the categorization to a case study…”
