Patch 1: Remove unused IO emulation functions Patch 2: Remove other unused stuff, which could be split up further for each C file and header Patch 3: Change DEBUG ifdefs to #if 0 The purpose of patch 3 is bogus, because the follow-up patch will be called removed useless #if 0 stuff.

If they ifdefs are not acceptable I will make this code dependent on a module parameter and compile it into the production module. We have a lot of different devices from different vendors out there and people report stuff isn't working but almost nothing more. You are misunderstanding this part of my patch. It does NOT remove used debug code. It does #if 0 code that was not used with CONFIG_ZD1211RW_DEBUG=y. The problem with patch 1 and 2 is, that almost all of the function are completing the interface and some of them are even only static inlines. They are there because they should be used, before somebody reinvents the wheel or makes something completely stupid. However if such reasoning is not acceptable I'm ready to compromise. I've only #if 0'ed static inline functions when they were the only user of an otherwise unused global function. The main question is what your should be used means. Will they be used within the next days/weeks or only in some far future? In the first case, I agree that my patch shouldn't be applied now. In the latter case, there's no reason to bloat the kernel binary now for some future usage that might or might not happen. Uli Kunitz cu Adrian -- Is there not promise of rain?
