Fri, 24 Apr 2026 13:46:03 +0200

selftest: add tests for O_EMPTYPATHAdd tests for the new O_EMPTYPATH flag of openat(2)/openat2(2).Also, the current openat2 tests include a helper header file thatdefines the necessary structs and constants to use openat2(2), such asstruct open_how. This may result in conflicting definitions when thesystem header openat2.h is present as well.So add openat2.h generated by 'make headers' to the uapi headerfiles in ./tools/include and remove the helper file definitions ofthe current openat2 selftests.Signed-off-by: Jori Koolstra Link: https://patch.msgid.link/20260424114611.1678641-3-jkoolstra@xs4all.nlSigned-off-by: Christian Brauner (Amutable) List of files: /linux/tools/testing/selftests/filesystems/openat2/helpers.h

Wed, 01 Apr 2026 02:28:05 +0200

selftests: openat2: migrate to kselftest harnessThese tests were written in the early days of selftests' TAP support,the more modern kselftest harness is much easier to follow and maintain.The actual contents of the tests are unchanged by this change. Most ofthe diff involves switching from the E_* syscall wrappers we previouslyused to ASSERT_EQ(fn(...), 0) in tests and helper functions.The first pass of the migration was done using Claude, followed by amanual rework and review.Assisted-by: Claude:claude-4.6-opusSigned-off-by: Aleksa Sarai Link: https://patch.msgid.link/20260401-openat2-selftests-kunit-v2-4-ad153a07da0c@amutable.comSigned-off-by: Christian Brauner (Amutable) List of files: /linux/tools/testing/selftests/filesystems/openat2/helpers.h

Wed, 01 Apr 2026 02:28:04 +0200

selftests: openat2: switch from custom ARRAY_LEN to ARRAY_SIZEFor whatever reason, the original version of the tests used a customversion of ARRAY_SIZE, but ARRAY_SIZE works just as well.Signed-off-by: Aleksa Sarai Link: https://patch.msgid.link/20260401-openat2-selftests-kunit-v2-3-ad153a07da0c@amutable.comSigned-off-by: Christian Brauner (Amutable) List of files: /linux/tools/testing/selftests/filesystems/openat2/helpers.h

Wed, 01 Apr 2026 02:28:03 +0200

selftests: openat2: move helpers to headerThis is a bit ugly, but in the next patch we will move to usingkselftest_harness.h -- which doesn't play well with being included inmultiple compilation units due to duplicate function definitions.Not including kselftest_harness.h would let us avoid this patch, but thehelpers will need include kselftest_harness.h in order to switch toTH_LOG.Signed-off-by: Aleksa Sarai Link: https://patch.msgid.link/20260401-openat2-selftests-kunit-v2-2-ad153a07da0c@amutable.comSigned-off-by: Christian Brauner (Amutable) List of files: /linux/tools/testing/selftests/filesystems/openat2/helpers.h

Wed, 01 Apr 2026 02:28:02 +0200

selftests: move openat2 tests to selftests/filesystems/These tests really should've always belonged there, doubly so now thatthey include a lot of other generic filesystem-related tests.Suggested-by: Christian Brauner Signed-off-by: Aleksa Sarai Link: https://patch.msgid.link/20260401-openat2-selftests-kunit-v2-1-ad153a07da0c@amutable.comSigned-off-by: Christian Brauner (Amutable) List of files: /linux/tools/testing/selftests/filesystems/openat2/helpers.h
