Currently, it uses the set->ops->walk() to iterate\nover these set elements. The existing set iterator skips inactive\nelements in the next generation, this does not work from the abort path\nto restore the original state since it has to skip active elements\ninstead (not inactive ones).\n\nThis patch moves the check for inactive elements to the set iterator\ncallback, then it reverses the logic for the .activate case which\nneeds to skip active elements.\n\nToggle
