That includes documentation, even though people, as always, care less about the docs than they do the code. As I understood it, the complaint with the tags you put in wasn't their existence, it was your putting GPLv2+ rather than straight GPLv2. In the absence of information to the contrary, you really have to assume the latter, since that's the overall license for the kernel. Thanks, jon
