Hi Cyril, Beside the tiny issues pointed out in [5|6]/7. The remaining part looks good to me. That would be awesome if you could help cleanup other ksm tests at the same time. Or, I help do that separately later on. (e.g. knob validation, add KSM kconfig, and remove 'merge_across_nodes' from ksm_common.h) Anyway, nice cleanup work! Reviewed-by: Li Wang -- Regards, Li Wang
