[PATCH] selftests/powerpc: fix spelling errors across test sources

by Nikil Paul S

Fix a number of minor spelling mistakes in selftests/powerpc sources, including ptrace, tm, pmu, math, alignment, and gzip tests. These changes improve readability of test messages and comments without affecting functionality as only comments were edited.

[PATCH] selftests: riscv: Add README for RISC-V KSelfTest

by Bala-Vignesh-Reddy

Add a README file for RISC-V specific kernel selftests under tools/testing/selftests/riscv/. This mirrors the existing README for arm64, providing clear guidance on how the tests are architecture specific and skipped on non-riscv systems. It also includes standard make commands for building, running and installing the tests, along with a reference to general kselftest documentation.

next-20250818: rust: `ARCH_KMALLOC_MINALIGN` is defined multiple times

by Naresh Kamboju

Build regressions were detected on multiple architectures (arm, arm64, riscv) with the Linux next-20250818 tag when building with Rust-enabled configurations (rust-gcc and rust-clang) from selftests/rust/config. Duplicate definition of ARCH_KMALLOC_MINALIGN in Rust bindings is causing build failures across affected toolchains.

[Patch v4 0/2] test that rmap behaves as expected

by Wei Yang

As David suggested, currently we don't have a high level test case to verify the behavior of rmap. This patch set introduce the verification on rmap by migration. Patch 1 is a preparation to move ksm related operations into vm_util. Patch 2 is the new test case for rmap. Currently it covers following four scenarios: * anonymous page * shmem page * pagecache page * ksm page v3->v4: * rebase on mm-new(dd1510cefdfe) * "assert" -> "test that" in subject v2->v3: * handle ksm error return in worker * rebase on current mm-unstable v1->v2: * do check on file opening in init_global_file_handlers() * factor out ksm_merge() and ksm_unmerge() instead of partial of it * align the return value of helpers: 0 on success, -errno on error * skip instead of assert if numa not available * check ksm sys file before continue * use private anonymous map instead of shared map * check pfn instead of content * retry migrate * fault in region for each process by FORCE_READ() RFC->v1: * open file in function itself instead of pass fd as parameter * fault in the region by accessing it instead of print content Wei Yang (2): selftests/mm: put general ksm operation into vm_util selftests/mm: test that rmap behave as expected MAINTAINERS | 1 + tools/testing/selftests/mm/.gitignore | 1 + tools/testing/selftests/mm/Makefile | 3 + .../selftests/mm/ksm_functional_tests.c | 142 +----- tools/testing/selftests/mm/rmap.c | 433 ++++++++++++++++++ tools/testing/selftests/mm/run_vmtests.sh | 4 + tools/testing/selftests/mm/vm_util.c | 123 +++++ tools/testing/selftests/mm/vm_util.h | 7 + 8 files changed, 596 insertions(+), 118 deletions(-) create mode 100644 tools/testing/selftests/mm/rmap.c -- 2.34.1

Hi all, This patch series addresses false positives in the generic mm selftests and skips tests that cannot run correctly due to missing features or system limitations. v3: https://lore.kernel.org/all/20250729053403.1071807-1-aboorvad@linux.ibm.com/ Changes in v4: - Rebased onto the latest mm-new branch, top commit of the base is commit 916e1f041670 ("drivers/base: move memory_block_add_nid() into the caller"). Dropped the v3 patches that had already been merged and re-applied them to the mm-new branch. - Only Patch 4 is updated to address review comments, all other patches remain unchanged from v3. --- v2: https://lore.kernel.org/all/20250703060656.54345-1-aboorvad@linux.ibm.com/ Changes in v3: - Rebased onto the latest mm-new branch, top commit of the base is commit 0709ddf8951f ("mm: add zblock allocator"). - Minor refactor based on the review comments. - Included the tags from the previous version. --- v1: https://lore.kernel.org/all/20250616160632.35250-1-aboorvad@linux.ibm.com/ Changes in v2: - Rebased onto the mm-new branch, top commit of the base is commit 3b4a8ad89f7e ("mm: add zblock allocator"). - Split some patches for clarity. - Updated virtual_address_range test to support testing 4PB VA on PPC64. - Added proper Fixes: tags. - Included a patch to skip a failing userfaultfd test when unsupported, instead of reporting a failure. --- Please let us know if you have any further comments.
