Ah, sorry I misinterpreted your suggestion (I thought that at the end of the day you wanted the macro to be less intrusive, so we change less code, that's why I interpreted it the way described in the Changelog). > But you figured out how to do > it, and having one name is even better, so thanks for that extra work!

Btw, can you actually drop patch 7, please? After I have updated the documentation I have realised that why the first chunk is invalid. It needs mode careful check and rework. > I omitted > > [1/7] kernel.h: Split out COUNT_ARGS() and CONCATENATE()" > > only because it's not essential to this series and has only a trivial > one-line impact on include/linux/pci.h. I'm not sure I understood what exactly "essentiality" means to you, but I included that because it makes the split which can be used later by others and not including kernel.h in the header is the objective I want to achieve. Without this patch the achievement is going to be deferred. Yet, this, as you have noticed, allows to compile and use the macros in the rest of the patches. P.S. Thank you for the review and application of the rest! -- With Best Regards, Andy Shevchenko
