selftests/pstore: add pstore test scripts going with reboot
To test pstore in earnest, we have to cause kernel crash and check pstore filesystem after reboot. We add two scripts: - pstore_crash_test This script causes kernel crash and reboot. It is executed by 'make run_pstore_crash' in selftests. It can also be used with kdump. - pstore_post_reboot_tests This script includes test cases which check pstore's behavior after crash and reboot. It is executed together with pstore_tests by 'make run_tests [-C pstore]' in selftests. The test cases in pstore_post_reboot_tests are currently following. - Check pstore backend is registered - Mount pstore filesystem - Check dmesg/console/pmsg files exist in pstore filesystem - Check dmesg/console files contain oops end marker - Check pmsg file properly keeps the content written before crash - Remove all files in pstore filesystem Example usage is following.
