The reason is that when a new test +gets added to test existing code to regression test a bug, we should be +able to run that test on an older kernel. Hence, it is important to keep +code that can still test an older kernel and make sure it skips the test +gracefully on newer releases. + You can find additional information on Kselftest framework, how to write new tests using the framework on Kselftest wiki:
