[PATCH v7 0/3] Introduce KUNIT_EXPECT_MEMEQ and KUNIT_EXPECT_MEMNEQ macros

by Maíra Canal

Currently, in order to compare memory blocks in KUnit, the KUNIT_EXPECT_EQ or KUNIT_EXPECT_FALSE macros are used in conjunction with the memcmp function, such as: KUNIT_EXPECT_EQ(test, memcmp(foo, bar, size), 0); Although this usage produces correct results for the test cases, if the expectation fails the error message is not very helpful, indicating only the return of the memcmp function. Therefore, create a new set of macros KUNIT_EXPECT_MEMEQ and KUNIT_EXPECT_MEMNEQ that compare memory blocks until a determined size. In case of expectation failure, those macros print the hex dump of the memory blocks, making it easier to debug test failures for memory blocks. The v7 has some formatting changes on the first patch and it was rebased on top of the mainline (due to 7089003304c6). The first patch of the series introduces the KUNIT_EXPECT_MEMEQ and KUNIT_EXPECT_MEMNEQ. The second patch adds an example of memory block expectations on the kunit-example-test.c. And the last patch replaces the KUNIT_EXPECT_EQ for KUNIT_EXPECT_MEMEQ on the existing occurrences.

[PATCH] selftests: vm: use 1 MB hugepage size for s390

by Gerald Schaefer

hugepage-vmemmap test fails for s390 because it assumes a hugepagesize of 2 MB, while we have 1 MB on s390. This results in iterating over two hugepages. If they are consecutive in memory, check_page_flags() will stumble over the additional head page. Otherwise, it will stumble over non-huge pageflags, after crossing the first 1 MB hugepage. Fix this by using 1 MB MAP_LENGTH for s390.

[PATCH v2 1/3] kunit: Provide a static key to check if KUnit is actively running tests

by David Gow

KUnit does a few expensive things when enabled. This hasn't been a problem because KUnit was only enabled on test kernels, but with a few people enabling (but not _using_) KUnit on production systems, we need a runtime way of handling this. Provide a 'kunit_running' static key (defaulting to false), which allows us to hide any KUnit code behind a static branch. This should reduce the performance impact (on other code) of having KUnit enabled to a single NOP when no tests are running. Note that, while it looks unintuitive, tests always run entirely within __kunit_test_suites_init(), so it's safe to decrement the static key at the end of this function, rather than in __kunit_test_suites_exit(), which is only there to clean up results in debugfs. Signed-off-by: David Gow <davidgow(a)google.com> --- This should be a no-op (other than a possible performance improvement) functionality-wise, and lays the groundwork for a more optimised static stub implementation. The remaining patches in the series add a kunit_get_current_test() function which is a more friendly and performant wrapper around current->kunit_test, and use this in the slub test. They also improve the documentation a bit. If there are no objections, we'll take the whole series via the KUnit tree.
