When ftrace test is skipped because of unmet dependencies and/or unsupported configuration, it returns 0 which is treated as a pass by the Kselftest framework. This leads to false positive result even when the test could not be run.
Change it to return kselftest skip code when a test gets skipped to clearly report that the test could not be run.
Kselftest framework SKIP code is 4 and the framework prints appropriate messages to indicate that the test is skipped.
I'm fine with this change, but I believe Masami and perhaps others have scripts that expect zero return.
If anything, we probably need to have a way to override the ksft_skip via a command line argument.
Masami?
