If you actually chase through the code, you'll see that when you change a module_param() variable, the module itself handles the parsing and then the saving of the new value - which allows it to do any locking needed and any cleanup of data that is required. > SO i was hoping i can do it from drivers aswell. The obvious first question is: "Why are you trying to change a module's variables from behind it's back, from another module?" There's no formal API for it, mostly because we don't usually create APIs to support Usually Bad Ideas.
