Subject[PATCH 4.4 06/79] selftests: zram: return Kselftest Skip code for skipped tests
Date
4.4-stable review patch.  If anyone has any objections, please let me know.

------------------

From: "Shuah Khan (Samsung OSG)" <shuah@kernel.org>

[ Upstream commit 685814466bf8398192cf855415a0bb2cefc1930e ]

When zram 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.

Kselftest framework SKIP code is 4 and the framework prints appropriate
messages to indicate that the test is skipped.
