224f1292615079d604651915a214f9e5ace9e41c - selftests/mm: add folio_split() and filemap_get_entry() race test

Mon, 23 Mar 2026 17:37:17 +0100

selftests/mm: add folio_split() and filemap_get_entry() race testThe added folio_split_race_test is a modified C port of the race conditiontest from [1]. The test creates shmem huge pages, where the main threadpunches holes in the shmem to cause folio_split() in the kernel and a setof 16 threads reads the shmem to cause filemap_get_entry() in the kernel. filemap_get_entry() reads the folio and xarray split by folio_split()locklessly. The original test[2] is written in rust and uses memfd (shmembacked). This C port uses shmem directly and use a single process.Note: the initial rust to C conversion is done by Cursor.Link: https://lore.kernel.org/all/CAKNNEtw5_kZomhkugedKMPOG-sxs5Q5OLumWJdiWXv+C9Yct0w@mail.gmail.com/ [1]Link: https://github.com/dfinity/thp-madv-remove-test [2]Link: https://lkml.kernel.org/r/20260323163717.184107-1-ziy@nvidia.comCo-developed-by: Bas van Dijk Signed-off-by: Bas van Dijk Co-developed-by: Adam Bratschi-Kaye Signed-off-by: Adam Bratschi-Kaye Signed-off-by: Zi Yan Cc: Baolin Wang Cc: Barry Song Cc: David Hildenbrand Cc: Dev Jain Cc: Hugh Dickins Cc: Lance Yang Cc: Liam Howlett Cc: Lorenzo Stoakes Cc: Matthew Wilcox (Oracle) Cc: Michal Hocko Cc: Mike Rapoport Cc: Nico Pache Cc: Ryan Roberts Cc: Shuah Khan Cc: Suren Baghdasaryan Cc: Vlastimil Babka Signed-off-by: Andrew Morton List of files: /linux/tools/testing/selftests/mm/Makefile

ff4ef2fbd10192357da76fd80796b7262df21b78 - selftests/mm: add memory failure anonymous page test

Fri, 06 Feb 2026 04:16:37 +0100

selftests/mm: add memory failure anonymous page testPatch series "selftests/mm: add memory failure selftests", v4.Introduce selftests to validate the functionality of memory failure. These tests help ensure that memory failure handling for anonymous pages,pagecaches pages works correctly, including proper SIGBUS delivery to userprocesses, page isolation, and recovery paths.Currently madvise syscall is used to inject memory failures. And onlyanonymous pages and pagecaches are tested. More test scenarios, e.g. hugetlb, shmem, thp, will be added. Also more memory failure injectingmethods will be supported, e.g. APEI Error INJection, if required.This patch (of 3):This patch adds a new kselftest to validate memory failure handling foranonymous pages. The test performs the following operations:1. Allocates anonymous pages using mmap().2. Injects memory failure via madvise syscall.3. Verifies expected error handling behavior.4. Unpoison memory.This test helps ensure that memory failure handling for anonymous pagesworks correctly, including proper SIGBUS delivery to user processes, pageisolation and recovery paths.Link: https://lkml.kernel.org/r/20260206031639.2707102-1-linmiaohe@huawei.comLink: https://lkml.kernel.org/r/20260206031639.2707102-2-linmiaohe@huawei.comSigned-off-by: Miaohe Lin Cc: David Hildenbrand Cc: Liam Howlett Cc: Lorenzo Stoakes Cc: Mark Brown Cc: Michal Hocko Cc: Mike Rapoport Cc: Naoya Horiguchi Cc: Shuah Khan Cc: Suren Baghdasaryan Cc: Vlastimil Babka Cc: kernel test robot Signed-off-by: Andrew Morton List of files: /linux/tools/testing/selftests/mm/Makefile

selftests/mm: have the harness run each test category separatelyAt present the mm selftests are integrated into the kselftest harness byhaving it run run_vmtest.sh and letting it pick it's default set of teststo invoke, rather than by telling the kselftest framework about each testprogram individually as is more standard. This has some unfortunateinteractions with the kselftest harness: - If any of the tests hangs the harness will kill the entire mm selftests run rather than just the individual test, meaning no further tests get run. - The timeout applied by the harness is applied to the whole run rather than an individual test which frequently leads to the suite not being completed in production testing.Deploy a crude but effective mitigation for these issues by telling thekselftest framework to run each of the test categories that run_vmtests.shhas separately. Since kselftest really wants to run test programs this isdone by providing a trivial wrapper script for each categorty that invokesrun_vmtest.sh, this is not a thing of great elegence but it is clear andsimple. Since run_vmtests.sh is doing runtime support detection, scenarioenumeration and setup for many of the tests we can't consistently tell theframework about the individual test programs.This has the side effect of reordering the tests, hopefully the testingis not overly sensitive to this.Link: https://lkml.kernel.org/r/20260123-selftests-mm-run-suites-separately-v2-1-3e934edacbfa@kernel.orgSigned-off-by: Mark Brown Reviewed-by: Lorenzo Stoakes Cc: David Hildenbrand Cc: Jason Gunthorpe Cc: Leon Romanovsky Cc: Liam Howlett Cc: Michal Hocko Cc: Mike Rapoport Cc: Shuah Khan Cc: Suren Baghdasaryan Cc: Vlastimil Babka Signed-off-by: Andrew Morton List of files: /linux/tools/testing/selftests/mm/Makefile

dd2c6ec24fca9235ccd1b9bfd382d0ddb419e41a - selftests/mm: remove virtual_address_range test

Fri, 16 Jan 2026 14:20:53 +0100

selftests/mm: remove virtual_address_range testThis self test is asserting internal implementation details and is highlyvulnerable to internal kernel changes as a result.It is currently failing locally from at least v6.17, and it seems that itmay have been failing for longer in many configurations/hardware as itskips if e.g. CONFIG_ANON_VMA_NAME is not specified.With these skips and the fact that run_vmtests.sh won't run the tests incertain configurations it is likely we have simply missed this test beingbroken in CI for a long while.I have tried multiple versions of these tests and am unable to find aworking bisect as previous versions of the test fail also.The tests are essentially mmap()'ing a series of mappings with no hint andasserting what the get_unmapped_area*() functions will come up with, withseemingly few checks for what other mappings may already be in place.It then appears to be mmap()'ing with a hint, and making a series ofsimilar assertions about the internal implementation details of thehinting logic.Commit 0ef3783d7558 ("selftests/mm: add support to test 4PB VA on PPC64"),commit 3bd6137220bb ("selftests/mm: virtual_address_range: avoid readingfrom VM_IO mappings"), and especially commit a005145b9c96 ("selftests/mm:virtual_address_range: mmap() without PROT_WRITE") are good examples ofthe whack-a-mole nature of maintaining this test.The last commit there being particularly pertinent as it was accountingfor an internal implementation detail change that really should have nobearing on self-tests, that is commit e93d2521b27f ("x86/vdso: Splitvirtual clock pages into dedicated mapping").The purpose of the mm self-tests are to assert attributes about the APIexposed to users, and to ensure that expectations are met.This test is emphatically not doing this, rather making a series ofassumptions about internal implementation details and asserting them.It therefore, sadly, seems that the best course is to remove this testaltogether.Link: https://lkml.kernel.org/r/20260116132053.857887-1-lorenzo.stoakes@oracle.comSigned-off-by: Lorenzo Stoakes Acked-by: SeongJae Park Cc: David Hildenbrand Cc: Liam Howlett Cc: Mark Brown Cc: Michal Hocko Cc: Mike Rapoport Cc: Shuah Khan Cc: Suren Baghdasaryan Cc: Vlastimil Babka Signed-off-by: Andrew Morton List of files: /linux/tools/testing/selftests/mm/Makefile

7f532d19c8be76ad2fcd7ab6b0c9eb618f70966b - selftests/mm: pass down full CC and CFLAGS to check_config.sh

Thu, 22 Jan 2026 18:02:18 +0100

selftests/mm: pass down full CC and CFLAGS to check_config.shcheck_config.sh checks that liburing is available by running the compilerprovided as its first argument. This makes two assumptions:1. CC consists of only one word2. No extra flag is requiredUnfortunately, there are many situations where these assumptions don'thold. For instance:- When using Clang, CC consists of multiple words- When cross-compiling, extra flags may be required to allow the compiler to find headersRemove these assumptions by passing down CC and CFLAGS as-is from theMakefile, so that the same command line is used as when actually buildingthe tests.Link: https://lkml.kernel.org/r/20260122170224.4056513-4-kevin.brodsky@arm.comSigned-off-by: Kevin Brodsky Reviewed-by: Mark Brown Acked-by: David Hildenbrand (Red Hat) Cc: Jason Gunthorpe Cc: John Hubbard Cc: Dev Jain Cc: Lorenzo Stoakes Cc: Paolo Abeni Cc: Ryan Roberts Cc: SeongJae Park Cc: Shuah Khan Cc: Usama Anjum Cc: wang lian Cc: Yunsheng Lin Signed-off-by: Andrew Morton List of files: /linux/tools/testing/selftests/mm/Makefile
