Device drivers are internal to the kernel, not external. Maybe you mean "third party", and not "external"? When I see "external code depending on kernel structures...", I inevitably think of "ps" and similar code that has to be recompiled when the kernel data structures change because some idiot thought it's be a good idea to read the KVA space instead of implementing a procedural interface that wouldn't change between structure revs. Terry Lambert terry@lambert.org --- Any opinions in this posting are my own and not those of my present or previous employers.
