In this series, I'm trying to add 3 missing tests to vm_runtests.sh which is used to run all the tests in mm suite. These tests weren't running by CIs. While enabling them and through review feedback, I've fixed some problems in tests as well. I've found more flakiness in more tests which I'll be fixing with future patches. hugetlb-read-hwpoison test is being added where it can only run with newly added "-d" (destructive) flag only. Not sure why it is failing again. So once it become stable, we can think of moving it to default set of tests if it doesn't have any side-effect to them. Cc: Ryan Roberts <ryan.roberts@xxxxxxx> Cc: Andrew Morton <akpm@xxxxxxxxxxxxxxxxxxxx> --- Changes in v3: - Add cover letter - Fix flakiness in tests found during enablement - Move additional tests down in the file - Add "-d" option which poisons the pages and aren't being useable after the test v2: https://lore.kernel.org/all/20240123073615.920324-1-usama.anjum@xxxxxxxxxxxxx Muhammad Usama Anjum (5): selftests/mm: hugetlb_reparenting_test: do not unmount selftests/mm: run_vmtests: remove sudo and conform to tap selftests/mm: save and restore nr_hugepages value selftests/mm: protection_keys: save/restore nr_hugepages settings selftests/mm: run_vmtests.sh: add missing tests tools/testing/selftests/mm/Makefile | 5 +++ .../selftests/mm/charge_reserved_hugetlb.sh | 4 +++ .../selftests/mm/hugetlb_reparenting_test.sh | 9 +++-- tools/testing/selftests/mm/on-fault-limit.c | 36 +++++++++---------- tools/testing/selftests/mm/protection_keys.c | 34 ++++++++++++++++++ tools/testing/selftests/mm/run_vmtests.sh | 10 +++++- 6 files changed, 76 insertions(+), 22 deletions(-) -- 2.42.0
