They'd be accessible from any other files you linked into the module (currently there are no such files). They're not visible outside the module because they're not EXPORTed. Making them static does lead to them getting eliminated, and 'static volatile' seems both gross and like something checkpatch would complain about. I'll leave them as they are but stick a kasan_ prefix on them just for the additional tidiness. Regards, Daniel
