I think it would rather complicate mode activation and de-activation but since there is no detail about how this will complicate group setup it is difficult to compare. It is difficult to reason about a patch when the motivation is vague. > teardown, while exposing them on every group would show empty files "show empty files" - technically these files, as they are implemented, will not be empty but return errors > with no clear purpose. > > Add a hidden property to struct rftype to hide files at creation. Missing a "why". This can append to describe how this adds the foundational support in preparation for features to restore visibility when the feature's files need to be exposed to user space. > > Suggested-by: Reinette Chatre > Signed-off-by: Babu Moger > --- Reinette
