selftests: membarrier: Fix incorrect kernel headers search path

2023-03-10T08:29:38Z

commit 498bb027726371ba4a94686d251f9be1d437573e upstream. 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

2019-09-25T15:42:31Z

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: remove duplicated all and clean target

2017-01-05T20:41:35Z

Currently, kselftest use TEST_PROGS, TEST_PROGS_EXTENDED, TEST_FILES to indicate the test program, extended test program and test files. It is easy to understand the purpose of these files. But mix of compiled and uncompiled files lead to duplicated "all" and "clean" targets. In order to remove the duplicated targets, introduce TEST_GEN_PROGS, TEST_GEN_PROGS_EXTENDED, TEST_GEN_FILES to indicate the compiled objects. Also, the later patch will make use of TEST_GEN_XXX to redirect these files to output directory indicated by KBUILD_OUTPUT or O. And add this changes to "Contributing new tests(details)" of Documentation/kselftest.txt. Signed-off-by: Bamvor Jian Zhang Signed-off-by: Shuah Khan

membarrier: clean up selftest

2015-09-22T22:09:53Z

We don't need to specify an explicit rule in the Makefile, the implicit one will do the same. The "__EXPORTED_HEADERS__" define is not needed, because we build the test against the installed kernel headers, not the in-tree kernel headers. Re-use "$(TEST_PROGS)" in the clean target rather than spelling the executable name twice. Include rather than the rather specific . Include rather than . In both cases, the former header is located in a standard location and includes the latter.
