| * 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 |
