So this concerns a physical build option! Anything that makes that clear (like your alternative does) is fine with me. (Perhaps "is pre-configured" could be "functions", as that's less ambiguous in a Kconfig file, but that's debatable.) > > All module parameters have a sysfs visibility (or permission) of zero. > > Why is that?

Greg already explained that it's OK to leave the code as is for now (since all these control knobs need to be provided via "real" sysfs files in the long run anyhow).
