Its filename was selftests-mm-hugetlb-read-hwpoison-add-sigbus-handler.patch This patch was dropped because it was merged into the mm-stable branch of git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm ------------------------------------------------------ From: "Mike Rapoport (Microsoft)" Subject: selftests/mm: hugetlb-read-hwpoison: add SIGBUS handler Date: Mon, 11 May 2026 19:27:45 +0300 Patch series "make MM selftests more CI friendly", v4. There's a lot of dancing around HugeTLB settings in run_vmtests.sh. Some test need just a few default huge pages, some require at least 256 MB, and some just skip lots of tests if huge pages of all supported sizes are not available. The goal of this set is to make tests deal with HugeTLB setup and teardown. There are already convenient helpers that allow easy reading and writing of /proc and /sysfs, so adding a few APIs that will detect and update HugeTLB settings shouldn't be a big deal. But these nice helpers use kselftest framework, and many of HugeTLB (and even THP) test don't, so as a result this patchset also includes a lot of churn for conversion of those tests to kselftest framework (patches 7-19). The series break out: patches 1-5: small fixes patch 6: merge of hugetlb mmap tests patch 7: renaming of hugepage-* to hugetlb-* patches 8-21: mechanical conversion to kselftest framework patches 22-28: extension of thp_settings to hugepage_settings to also include HugeTLB helpers patches 29-30: add helpers for setting up SHM limits in hugetlb-shm and thuge-gen tests patches 31-53: integrate the new APIs in all the tests that use HugeTLB patches 54-55: drop HugeTLB setup from run_vmtests.sh This patch (of 55): Injection of a memory error with madvise() causes SIGBUS, which terminates the hugetlb-read-hwpoison test prematurely. Add a dummy SIGBUS handler to allow the test to continue regardless of SIGBUS.
