From mboxrd@z Thu Jan 1 00:00:00 1970 From: shuah at kernel.org (Shuah Khan (Samsung OSG)) Date: Fri, 4 May 2018 19:13:07 -0600 Subject: [PATCH 03/24] selftests: cpu-hotplug: return Kselftest Skip code for skipped tests In-Reply-To: <20180505011328.32078-1-shuah@kernel.org> References: <20180505011328.32078-1-shuah@kernel.org> Message-ID: <20180505011328.32078-3-shuah@kernel.org> When cpu-on-off-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.
