No i was trying to avoid having to touch those other 4 existing macros,
touching lines that checkpatch.pl and you will pick on again. Adding
the prefixes just to those new ones would be inconsistent and also not
nice.

It is a bit unfortunate that you seem to be surprised where i said i
was going to not address this. And once the new series comes insist on
another round ... which involves testing and what not.

But hey, i will send a v6 with style refactoring patches and test it
all over again.

Thanks everyone for the review, i hope that next version will be
acceptable and not open new discussion with the new patches coming.

regards,
Henning
