Versions: - V4: - no changes to first patch - Changed header documentation - Fixed includes - Renamed create_memory() to verify_ksm(), orignal verify_ksm() has been removed - Remove loop in verify_ksm - Remove wait at the end - Call madvise at the end of the function - Remove needs_fork - V3: - Disable smart scan for ksm05 and ksm06 - add ksm07 to runtest/mm - change documentation format in header of ksm07.c - Move function create_memory_for_smartscan() to ksm07.c - Rename create_memory_for_smartscan() to create_memory() - V2: - Disable smart_scan in the test setup structure - Remove the changes in create_same_memory() - Add the new testcase ksm07 for the smart scan test *** BLURB HERE *** Stefan Roesch (2): mem: disable KSM smart scan for ksm tests add ksm test for smart-scan feature runtest/mm | 1 + testcases/kernel/mem/.gitignore | 1 + testcases/kernel/mem/ksm/ksm01.c | 2 + testcases/kernel/mem/ksm/ksm02.c | 2 + testcases/kernel/mem/ksm/ksm03.c | 2 + testcases/kernel/mem/ksm/ksm04.c | 2 + testcases/kernel/mem/ksm/ksm05.c | 2 + testcases/kernel/mem/ksm/ksm06.c | 2 + testcases/kernel/mem/ksm/ksm07.c | 113 +++++++++++++++++++++++++++++++ 9 files changed, 127 insertions(+) create mode 100644 testcases/kernel/mem/ksm/ksm07.c base-commit: 8c89ef3d451087ed6e18750bd5eedd10e5ab3d2e -- 2.39.3 -- Mailing list info: https://lists.linux.it/listinfo/ltp
