exporting symbols in kernel only when a module is compiled?
Ok, I'm sure this isn't limited to tcp_hashinfo, but does it make sense to only export some symbols if "x" module is compiled into the kernel?
For example with tcp_hashinfo, its only exported if ipv6 is compiled as a module. So if one statically compiles in ipv6 or doesnt compile it at all, its not available to any other modules. Is there a good reason for it here? Are there other similiar situations with other symbols? Should it be this way?
It's possible to get around with recompiling modules and System.map hackery, but should it be necessary?
thanks,

I think the major problem here is, that if you at first doesn't compile ipv6 at all, and later want to compile it as a module, it will not work. I think it would be better if choosing a feature as module or not compiled at all doesn't change anything in the kernel.
