From f9fedb2719b1aed80f8e614b2b1f54df94ae1ebb Mon Sep 17 00:00:00 2001 From: "Shuah Khan (Samsung OSG)" Date: Fri, 4 May 2018 11:38:40 -0600 Subject: selftests: locking: return Kselftest Skip code for skipped tests When locking 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 search for ww_mutex module and return skip code if it isn'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.
