selftests: membarrier: Fix incorrect kernel headers search path

2023-02-13T16:09:45+00:00

Use $(KHDR_INCLUDES) as lookup path for kernel headers. This prevents building against kernel headers from the build environment in scenarios where kernel headers are installed into a specific output directory (O=...).

selftests, sched/membarrier: Add multi-threaded test

2019-09-25T15:42:31+00:00

membarrier commands cover very different code paths if they are in a single-threaded vs multi-threaded process. Therefore, exercise both scenarios in the kernel selftests to increase coverage of this selftest.

selftests: Add test plan API to kselftest.h and adjust callers

2019-04-25T19:15:46+00:00

The test plan for TAP needs to be declared immediately after the header. This adds the test plan API to kselftest.h and updates all callers to declare their expected test counts. Signed-off-by: Kees Cook Signed-off-by: Shuah Khan

selftests: membarrier: return Kselftest Skip code for skipped tests

2018-05-30T21:29:06+00:00

When membarrier 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. Change it to use ksft_exit_skip() when the test is skipped. Signed-off-by: Shuah Khan (Samsung OSG)
