[RFC PATCH 0/4] kunit: more assertion reworking

by Daniel Latypov

This is a follow up to these three series: https://lore.kernel.org/all/20220113165931.451305-1-dlatypov@google.com/ https://lore.kernel.org/all/20220118223506.1701553-1-dlatypov@google.com/ https://lore.kernel.org/all/20220125210011.3817742-1-dlatypov@google.com/ The two goals of those series were a) reduce the size of struct kunit_assert and friends. (struct kunit_assert went from 48 => 8 bytes on UML.) b) simplify the internal code, mostly by deleting macros This series goes further a) sizeof(struct kunit_assert) = 0 now b) e.g. we delete another class of macros (KUNIT_INIT_*_ASSERT_STRUCT) Note: this does change the function signature of kunit_do_failed_assertion, so we'd need to update the rust wrapper in https://github.com/Rust-for-Linux/linux/blob/rust/rust/kernel/kunit.rs But otherwise, I don't think this series changes anything on the rust-side. Daniel Latypov (4): rfc: kunit: remove format func from struct kunit_assert, get it to 0 bytes rfc: kunit: rename base KUNIT_ASSERTION macro to _KUNIT_FAILED rfc: kunit: eliminate KUNIT_INIT_*_ASSERT_STRUCT macros kunit: delcare kunit_assert structs as const include/kunit/assert.h | 74 ++----------------------- include/kunit/test.h | 123 ++++++++++++++++++++++------------------- lib/kunit/test.c | 7 ++- 3 files changed, 76 insertions(+), 128 deletions(-) base-commit: e7eaffce47b7db72b077630dbe836f0c4132496d -- 2.36.1.124.g0e6072fb45-goog

[PATCH v3 0/5] memcontrol selftests fixups

by Michal Koutný

Hello. I'm just flushing the patches to make memcontrol selftests check the events behavior we had consensus about (test_memcg_low fails). (test_memcg_reclaim, test_memcg_swap_max fail for me now but it's present even before the refactoring.) The two bigger changes are: - adjustment of the protected values to make tests succeed with the given tolerance, - both test_memcg_low and test_memcg_min check protection of memory in populated cgroups (actually as per Documentation/admin-guide/cgroup-v2.rst memory.min should not apply to empty cgroups, which is not the case currently. Therefore I unified tests with the populated case in order to to bring more broken tests). Thanks, Michal Changes from v2 (https://lore.kernel.org/r/20220518161859.21565-2-mkoutny@suse.com/) - rebased on mm-stable 02e34fff195d3a5f67cbb553795dc109a37d1dcf - collected acked-bys - proper Fixes: tag Changes from v1 (https://lore.kernel.org/r/20220513171811.730-1-mkoutny@suse.com/) - fixed mis-rebase in compilation fix patch, - added review, ack tags from v1, - applied feedback from v1 (Octave script in git tree), - added one more patch extracting common parts, - rebased on mm-stable bbe832b9db2e.

[PATCH v2 0/3] fat: add support for the renameat2 RENAME_EXCHANGE flag

by Javier Martinez Canillas

Hello, This series add support for the renameat2 system call RENAME_EXCHANGE flag (which allows to atomically replace two paths) to the vfat filesystem code. There are many use cases for this, but we are particularly interested in making possible for vfat filesystems to be part of OSTree [0] deployments. Currently OSTree relies on symbolic links to make the deployment updates an atomic transactional operation. But RENAME_EXCHANGE could be used [1] to achieve a similar level of robustness when using a vfat filesystem. Patch #1 is just a preparatory patch to introduce the RENAME_EXCHANGE support in patch #2 and finally patch #3 adds some kselftests to test it. This is a v2 that addresses issues pointed out in the first version that was posted as an RFC: https://lore.kernel.org/lkml/20220519092343.2776414-1-javierm@redhat.com/ [0]: https://github.com/ostreedev/ostree [1]: https://github.com/ostreedev/ostree/issues/1649 Changes in v2: - Only update the new_dir inode version and timestamps if != old_dir (Alex Larsson). - Add some helper functions to avoid duplicating code (OGAWA Hirofumi). - Use braces for multi-lines blocks even if are one statement (OGAWA Hirofumi). - Mention in commit message that the operation is as transactional as possible but within the vfat limitations of not having a journal (Colin Walters). - Call sync to flush the page cache before checking the file contents (Alex Larsson). - Drop RFC prefix since the patches already got some review. Javier Martinez Canillas (3): fat: add a vfat_rename2() and make existing .rename callback a helper fat: add renameat2 RENAME_EXCHANGE flag support selftests/filesystems: add a vfat RENAME_EXCHANGE test MAINTAINERS | 1 + fs/fat/namei_vfat.c | 193 +++++++++++++++++- tools/testing/selftests/Makefile | 1 + .../selftests/filesystems/fat/Makefile | 7 + .../testing/selftests/filesystems/fat/config | 2 + .../filesystems/fat/rename_exchange.c | 37 ++++ .../filesystems/fat/run_fat_tests.sh | 82 ++++++++ 7 files changed, 316 insertions(+), 7 deletions(-) create mode 100644 tools/testing/selftests/filesystems/fat/Makefile create mode 100644 tools/testing/selftests/filesystems/fat/config create mode 100644 tools/testing/selftests/filesystems/fat/rename_exchange.c create mode 100755 tools/testing/selftests/filesystems/fat/run_fat_tests.sh -- 2.36.1
