The final conclusion of the IRC discussion might have escaped me but wasn't there supposed to be a cast somewhere ?
There is a cast. The part "(x)" of "(~(x)0)" is the cast. And I don't think that there was a final conclusion. I am not really convinced that this should be part of batman-adv. Just look at include/linux/kernel.h for similar functionality (but with predefined types). Maybe this would be the correct position for such a macro? (I don't know it... just thinking out loud).
Kind regards, Sven
