Linux Kernel - Modifying a module_param variable from other drivers

Dear all, I see that when we declare a variable as module_param from a driver, i can see it listed in "/sys/module/xxx/parameters/...". Ex : /sys/module/usbcore/parameters/autosuspend we can modify and read it with echo and cat commands from terminal. But is there a way i can read this value from other drivers? Common sense says it should be there because if we are able to access them from user space, from kernel space we should definitely be able to do. Is it so? If yes, what are the API's? Posted teh same on SO - http://stackoverflow.com/questions/19973866/linux-kernel-modifying-a-module-... Reply either here or on SO. Regards, Sandeep
