4.17-stable review patch. If anyone has any objections, please let me know.
------------------
From: "Shuah Khan (Samsung OSG)" <shuah@xxxxxxxxxx>
[ Upstream commit 856e7c4b619af622d56b3b454f7bec32a170ac99 ]
When pstore_post_reboot test gets 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.
