BTW, these seemingly odd macro names come from BSD. Terefore they are quite readable for many of us :-) I don't know what to do with these patches, they feel like just plain noise to me even though I like the type checking. I'm going to defer for now, sorry. - To unsubscribe from this list: send the line unsubscribe netdev in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html

But what is the motivation for changing all the macro calls to function calls, when you have set up the marcos to call the appropriate functions? It's just a sequence that allows the kernel to compile. I expect to remove the macros when the other callsites, drivers/infiniband and drivers/parisc, are converted. Surely if you want to do that you should just ditch the marcos all together. Perhaps I am missing a patch? That's what I'd like to do but in sequence. David Miller can reasonably accept the net changes, but I'm not too sure he can accept the drivers changes. If/when this change is accepted and patches for drivers are accepted, I'll submit a patch to remove the macros.

I realised after I sent my mail that you were probably having to cope with other callers.
