* kcsan: Make test follow KUnit style recommendationsMarco Elver2021-03-081-1207/+0
| | | | | | | | | | | | | | | | | Per recently added KUnit style recommendations at Documentation/dev-tools/kunit/style.rst, make the following changes to the KCSAN test: 1. Rename 'kcsan-test.c' to 'kcsan_test.c'. 2. Rename suite name 'kcsan-test' to 'kcsan'. 3. Rename CONFIG_KCSAN_TEST to CONFIG_KCSAN_KUNIT_TEST and default to KUNIT_ALL_TESTS.

* kcsan: Test support for compound instrumentationMarco Elver2020-08-251-14/+51
| | | | | | | | | | | Changes kcsan-test module to support checking reports that include compound instrumentation. Since we should not fail the test if this support is unavailable, we have to add a config variable that the test can use to decide what to check for.

* kcsan: Prefer '__no_kcsan inline' in testMarco Elver2020-06-291-2/+2
| | | | | | | | | Instead of __no_kcsan_or_inline, prefer '__no_kcsan inline' in test -- this is in case we decide to remove __no_kcsan_or_inline. Suggested-by: Peter Zijlstra <peterz@infradead.org> Signed-off-by: Marco Elver <elver@google.com> Signed-off-by: Paul E. McKenney <paulmck@kernel.org>
* kcsan: Add test suiteMarco Elver2020-06-291-0/+1084
This adds KCSAN test focusing on behaviour of the integrated runtime. Tests various race scenarios, and verifies the reports generated to console. Makes use of KUnit for test organization, and the Torture framework for test thread control. Signed-off-by: Marco Elver <elver@google.com> Signed-off-by: Paul E. McKenney <paulmck@kernel.org>
