* This file will include user space functions that will drive
* the kernel module to test various functions and kernel
* calls. Each function will need to setup the tif structure
* so that the in parameters and out parameters are correctly
* initialized
*
* use tif structure for passing params between user
* space and kernel space, in some tests it is really not
* needed, and if nothing is needed to pass in utilize
* the ki_generic function below. the tif structure makes
* it easy to maintain all the tests if they have the same
* process in kernel space to read in params in the kernel
* module no matter what the test is
