Hi, What is the kernel policy on using "extern" to share variables between source files in a module? I've been looking at one subsystem in staging [that shares variables quite a bit] to becoming familar with it, and seeing if I can help do some work on it in my free time. Personally I prefer to see them eradicated (they polute the namespace), and store such variables in a context structure that is passed around. But I don't see any reference about it in the coding style, and I am not one to code-churn just because it's not my personal style! :) Thanks, Justin
