There are a bunch of these under tools/testing/selftests/lib/ that are all identical except for the test name. We can reduce code duplication and improve maintainability if we have one version of this. However kselftest requires an executable for each test. We can move all the script logic to a central script then have each individual test script set the module name and call the main script. There is a little bit of boilerplate left in each script to handle building/running tests with the O=/path/to/out make option. Add test runner creation script. Signed-off-by: Tobin C.
