> There is no way to specify DAMOS target regions with a deterministic
> time based age range. Extend DAMOS core filter to specify target
> regions with age in milliseconds. Introduce new damos_filter_type,
> DAMOS_FILTER_TYPE_AGE_MS in DAMON API, and implement support of the type

>
> Convert the age in aggregation intervals to milliseconds and use it when
> the filter is evaluated. Reuse damos_filter->range_{min,max} to save
