Did you check? Until this is tested, maybe it's best to prevent module unloading?

Did you check? Per the 0/N I've not got the capability to do run time testing for any of this stuff. And from previous discussions, ISTR that people didn't want to see a blanket block-unload policy implemented. > Until this is tested, maybe it's best to prevent module unloading? If that is what people want, I can add that. P.

We've exported the symbols that we know these specific drivers will need as tristate, so now we can make the conversion from bool to tristate w/o concern for build regressions.
