Are folio_test_large() and folio_is_zone_device() mutually exclusive?
If so then this is a false positive. Just ignore the warning in that
case.
The folio in ZONE_DEVICE is not a large folio, so there is no issue for now,
but will fix.
If it's not an issue, then don't feel obligated to do anything. These
are a one time email and then I treat it as addressed. These warnings
are intended to be useful, not a burden.
The check is great, and the new version avoids to pass the nr_pages, so
there is no more warning, thanks.
