For the C-files it's fine to include linux/* versions of asm/* ones, for the _headers_ I would prefer to be strictly minimalistic, because of possible header dependency hell. If something is defined in asm/* and some header wants to use that, it's better to include asm/*. -- With Best Regards, Andy Shevchenko
