Re: [PATCH v3] mm: add thp_utilization metrics to /proc/thp_utilization

Hi Yu,

I’ve updated your patch set from last year to work with folio and am testing it now. The functionality in split_huge_page() is the same as what I have. Was there any follow up work done later? 

If not, I would like to incorporate this into what I have, and then resubmit. Will reference the original patchset. We need this functionality for the shrinker, but even the changes to split_huge_page() by itself it should show some performance improvement when used by the existing deferred_split_huge_page(). 

Thanks,
Alex
