I think we're getting confused. What I'm advocating is something like this: init_module() { struct mixer_levels *levels; levels = inter_module_get("mysoundcard_mixerlevels"); if (!levels) /* We haven't been loaded before. Default to zero */ levels = &default_levels; init_hardware(levels); } cleanup_module() { struct mixer_levels *levels = kmalloc(sizeof *levels); if (levels) { /* Record current the levels so we can init the hardware to the same next time we're loaded */ memcpy(levels, current_levels, sizeof(*levels)); inter_module_register("mysoundcard_mixerlevels", levels); } } (Note it's pseudocode. I _know_ it doesn't compile and that the name we pass to inter_module_register is removed when the module is unloaded. Oh and that inter_module_register will panic() and kill the whole system on the second unload because a registration with that name already exists.) -- dwmw2 - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] Please read the FAQ at http://www.tux.org/lkml/
