Its filename was selftests-mm-guard-regions-skip-collapse-test-when-thp-not-enabled.patch This patch was dropped because an updated version will be issued ------------------------------------------------------ From: Chunyu Hu Subject: selftests/mm/guard-regions: skip collapse test when thp not enabled Date: Mon, 30 Mar 2026 23:14:57 +0800 Patch series "selftests/mm: skip several tests when thp is not available", v7. There are several tests requires transprarent hugepages, when run on thp disabled kernel such as realtime kernel, there will be false negative. Mark those tests as skip when thp is not available. This patch (of 7): When thp is not available, just skip the collape tests to avoid the false negative. Without the change, run with a thp disabled kernel: ./run_vmtests.sh -t madv_guard -n 1 # RUN guard_regions.anon.collapse ... # guard-regions.c:2217:collapse:Expected madvise(ptr, size, MADV_NOHUGEPAGE) (-1) == 0 (0) # collapse: Test terminated by assertion # FAIL guard_regions.anon.collapse not ok 2 guard_regions.anon.collapse # RUN guard_regions.shmem.collapse ... # guard-regions.c:2217:collapse:Expected madvise(ptr, size, MADV_NOHUGEPAGE) (-1) == 0 (0) # collapse: Test terminated by assertion # FAIL guard_regions.shmem.collapse not ok 32 guard_regions.shmem.collapse # RUN guard_regions.file.collapse ... # guard-regions.c:2217:collapse:Expected madvise(ptr, size, MADV_NOHUGEPAGE) (-1) == 0 (0) # collapse: Test terminated by assertion # FAIL guard_regions.file.collapse not ok 62 guard_regions.file.collapse # FAILED: 87 / 90 tests passed. # 17 skipped test(s) detected.
