Subject: Re: [RFC PATCH 2/6] mm/damon/vaddr: advance migration attempt in folio level for filter out

> damos_va_migrate_pmd_entry() finds folios to migrate under the given
> pmd, using a loop for the pmd address range. The loop advances in page
> size if a given folio is excluded by DAMOS ops filters. DAMOS ops
> filters work in folio granularity. Hence it is more efficient and makes
> sense to advance in the folio size.
>
> Advance the loop in folio size for the ops filter out decision. For
> that, do the folio size based loop advancement offset update before
> applying DAMOS ops filters.
>
> Closes: https://sashiko.dev/#/bug/linux-67c34df7-6dfb-4e18-9ce0-0d26915e5785
