Howlett" , Vlastimil Babka , Mike Rapoport , Suren Baghdasaryan , Michal Hocko , Shuah Khan , Zi Yan Cc: linux-mm@kvack.org, linux-kselftest@vger.kernel.org, linux-kernel@vger.kernel.org, Qiliang Yuan X-Mailer: b4 0.13.0 run_vmtests.sh only creates the XFS that "khugepaged all:file" and the pagecache folio split cases of split_huge_page_test need when xfs is already registered, so with xfs built as a module and not loaded yet those tests are all skipped. Patch 1 adds load_module(), which records the modules the script loads and unloads them again before it exits, and moves hwpoison_inject over to it. Patch 2 loads xfs through it. Signed-off-by: Qiliang Yuan --- V1 -> V2: - Add load_module() and unload what the script loaded on exit (Zi Yan) - Unload xfs again after the run (Zi Yan) - Rebase onto mainline v1: https://lore.kernel.org/r/20261016-bug-selftests-mm-run-vmtests-xfs-modprobe-v1-1-b97dfc79e97a@gmail.com --- Qiliang Yuan (2): selftests/mm: track the modules run_vmtests.sh loads selftests/mm: load xfs before checking for it in run_vmtests.sh tools/testing/selftests/mm/run_vmtests.sh | 33 ++++++++++++++++++++++--------- 1 file changed, 24 insertions(+), 9 deletions(-) --- base-commit: 90201351a862182bdabfc1ad1c97b1e1b6ed5931 change-id: 20261016-bug-selftests-mm-run-vmtests-xfs-modprobe-de0697d4c4e9 Best regards, -- Qiliang Yuan
