Hi all, This series fixes a few issues in hmm-tests that show up when page-size and huge-page configuration differ from the hardcoded assumptions the tests were written for (PMD/THP sizing, default hugepage size, and related cases).
It also includes a fix to exclusive_cow: the test ignored the return value of fork(), so both parent and child ran the same teardown path. v1: https://lore.kernel.org/all/[email protected]/ Changes in v2: - Patches 1 and 3 are unchanged. - Patch 2: fall back to TWOMEG when read_pmd_pagesize() returns zero, use a fixed-size array to avoid non-constant initialisers, and skip benchmark sizes that exceed INT_MAX instead of capping the THP count at runtime. Please let us know if you have any comments. Thanks, Aboorva Aboorva Devarajan (1): selftests/mm: fix exclusive_cow test fork() handling Sayali Patil (2): selftests/mm: allow PUD-level entries in compound testcase of hmm tests selftests/mm: remove hardcoded THP sizing assumptions in hmm tests tools/testing/selftests/mm/hmm-tests.c | 104 ++++++++++++++++++------- 1 file changed, 76 insertions(+), 28 deletions(-) -- 2.54.0
