[PATCH] kunit: tool: don't print out test statuses w/ 0s in summary

by Daniel Latypov

Before: > Testing complete. Passed: 137, Failed: 0, Crashed: 0, Skipped: 36, Errors: 0 After: > Testing complete. Passed: 137, Skipped: 36 Even with our current set of statuses, the output is a bit verbose. It could get worse in the future if we add more (e.g. timeout, kasan). Let's only print the relevant ones. I had previously been sympathetic to the argument that always printing out all the statuses would make it easier to parse results. But now we have commit acd8e8407b8f ("kunit: Print test statistics on failure"), there are test counts printed out in the raw output. We don't currently print out an overall total across all suites, but it would be easy to add, if we see a need for that.

[PATCH v1] kunit: add support for kunit_suites that reference init code

by Brendan Higgins

Add support for a new kind of kunit_suite registration macro called kunit_test_init_suite(); this new registration macro allows the registration of kunit_suites that reference functions marked __init and data marked __initdata. Signed-off-by: Brendan Higgins <brendanhiggins(a)google.com> Tested-by: Martin Fernandez <martin.fernandez(a)eclypsium.com> Reviewed-by: Kees Cook <keescook(a)chromium.org> Reviewed-by: David Gow <davidgow(a)google.com> --- This is a follow-up to the RFC here[1]. This patch is in response to a KUnit user issue[2] in which the user was attempting to test some init functions; although this is a functional solution as long as KUnit tests only run during the init phase, we will need to do more work if we ever allow tests to run after the init phase is over; it is for this reason that this patch adds a new registration macro rather than simply modifying the existing macros. Changes since last version: - I added more to the kunit_test_init_suites() kernel-doc comment detailing "how" the modpost warnings are suppressed in addition to the existing information regarding "why" it is OK for the modpost warnings to be suppressed.

[PATCH] kunit: tool: cosmetic: don't specify duplicate kunit_shutdown's

by Daniel Latypov

Context: When using a non-UML arch, kunit.py will boot the test kernel with these options by default: > mem=1G console=tty kunit_shutdown=halt console=ttyS0 kunit_shutdown=reboot For QEMU, we need to use 'reboot', and for UML we need to use 'halt'. If you switch them, kunit.py will hang until the --timeout expires. So the code currently unconditionally adds 'kunit_shutdown=halt' but then appends 'reboot' when using QEMU (which overwrites it). This patch: Having these duplicate options is a bit noisy. Switch so we only add 'halt' for UML. I.e. we now get UML: 'mem=1G console=tty console=ttyS0 kunit_shutdown=halt' QEMU: 'mem=1G console=tty console=ttyS0 kunit_shutdown=reboot' Side effect: you can't overwrite kunit_shutdown on UML w/ --kernel_arg. But you already couldn't for QEMU, and why would you want to?

[PATCH V2] testing/selftests/mqueue: Fix mq_perf_tests to free the allocated cpu set

by Athira Rajeev

The selftest "mqueue/mq_perf_tests.c" use CPU_ALLOC to allocate CPU set. This cpu set is used further in pthread_attr_setaffinity_np and by pthread_create in the code. But in current code, allocated cpu set is not freed. Fix this issue by adding CPU_FREE in the "shutdown" function which is called in most of the error/exit path for the cleanup. Also add CPU_FREE in some of the error paths where shutdown is not called.

[PATCH v2 0/4] memcg: introduce per-memcg proactive reclaim

This patch series adds a memory.reclaim proactive reclaim interface. The rationale behind the interface and how it works are in the first patch. --- Changes in V2: - Add the interface to root as well. - Added a selftest. - Documented the interface as a nested-keyed interface, which makes adding optional arguments in the future easier (see doc updates in the first patch). - Modified the commit message to reflect changes and add a timeout argument as a suggested possible extension - Return -EAGAIN if the kernel fails to reclaim the full requested amount. --- Shakeel Butt (1): memcg: introduce per-memcg reclaim interface Yosry Ahmed (3): selftests: cgroup: return the errno of write() in cg_write() on failure selftests: cgroup: fix alloc_anon_noexit() instantly freeing memory selftests: cgroup: add a selftest for memory.reclaim Documentation/admin-guide/cgroup-v2.rst | 21 +++++ mm/memcontrol.c | 37 ++++++++ tools/testing/selftests/cgroup/cgroup_util.c | 11 ++- .../selftests/cgroup/test_memcontrol.c | 94 ++++++++++++++++++- 4 files changed, 156 insertions(+), 7 deletions(-) -- 2.35.1.1178.g4f1659d476-goog
