Nobody ever called this helper till the patch "mm/huge_memory: copy file THPs at fork like copy_present_ptes() does" in the current series, so there is no actual bug to fix in stables, so may be not to add extra work to stable trees maintainers? The other question is: what to do with the actual bug this series is addressed to. i don't think the significant rewrite of PMD handling is a good patch for stable, so may be we'll need to create a minimal fix like my 1st version to fix the existing problem - especially for stable trees. Or may be not to fix stables at all. But let's first finish with the proper fix/rewrite. One problem a time to solve. -- Cheers, Konstantin
