Various improvements/fixes for the mm kselftests: - Patch 1-3 extend support for more build configurations: out-of-tree $KDIR, cross-compilation, etc.
- Patch 4-7 fix issues related to faulting in pages, introducing a new helper for that purpose. - Patch 8 fixes the value returned by pagemap_ioctl (PASS was always returned, which explains why the issue fixed in patch 6 went unnoticed). - Patch 9 improves the exit code of pfnmap. Net results: - 1 test no longer fails (patch 7) - 3 tests are no longer skipped (patch 4) - More accurate return values for whole suites (patch 8, 9) - Extra tests are more likely to be built (patch 1-3) --- v2..v3: - Patch 5: new patch [David Hildenbrand] - Patch 6: make the helper take a number of pages + pagesize, rename to force_read_pages() [David] - Patch 7: improved page count calculation (avoiding floating-point helper) - Patch 7: added Fixes tag [David] - Patch 9: open the file only once and save the fd [David] - Collected R-b/A-b v2: https://lore.kernel.org/all/[email protected]/ v1..v2: - New patches: 1, 4, 5, 8 v1: https://lore.kernel.org/all/[email protected]/ --- Cc: Andrew Morton <[email protected]> Cc: David Hildenbrand <[email protected]> Cc: Dev Jain <[email protected]> Cc: Lorenzo Stoakes <[email protected]> Cc: Mark Brown <[email protected]> Cc: Ryan Roberts <[email protected]> Cc: Shuah Khan <[email protected]> --- Kevin Brodsky (9): selftests/mm: default KDIR to build directory selftests/mm: remove flaky header check selftests/mm: pass down full CC and CFLAGS to check_config.sh selftests/mm: fix usage of FORCE_READ() in cow tests selftests/mm: check that FORCE_READ() succeeded selftests/mm: introduce helper to read every page selftests/mm: fix faulting-in code in pagemap_ioctl test selftests/mm: fix exit code in pagemap_ioctl selftests/mm: report SKIP in pfnmap if a check fails tools/testing/selftests/mm/Makefile | 8 +- tools/testing/selftests/mm/check_config.sh | 3 +- tools/testing/selftests/mm/cow.c | 43 +++++++-- tools/testing/selftests/mm/hugetlb-madvise.c | 9 +- tools/testing/selftests/mm/page_frag/Makefile | 2 +- tools/testing/selftests/mm/pagemap_ioctl.c | 15 ++- tools/testing/selftests/mm/pfnmap.c | 93 +++++++++++-------- .../selftests/mm/split_huge_page_test.c | 6 +- tools/testing/selftests/mm/vm_util.h | 7 ++ 9 files changed, 109 insertions(+), 77 deletions(-) base-commit: 24d479d26b25bce5faea3ddd9fa8f3a6c3129ea7 -- 2.51.2
