If anyone has any objections, please let me know. ------------------ From: "Shuah Khan (Samsung OSG)" [ Upstream commit 8781578087b8fb8829558bac96c3c24e5ba26f82 ] When static_keys test is skipped because of unmet dependencies and/or unsupported configuration, it exits with error which is treated as a fail by the Kselftest framework. This leads to false negative 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. Added an explicit searches for test_static_key_base and test_static_keys modules and return skip code if they aren't found to differentiate between the failure to load the module condition and module not found condition. Kselftest framework SKIP code is 4 and the framework prints appropriate messages to indicate that the test is skipped.
