Subject: mm/damon/paddr: remove folio_sz field from damon_pa_access_chk_result
Date: Mon, 9 Jan 2023 21:33:34 +0000
DAMON physical address space monitoring operations set gets and saves size
of the folio for a given physical address inside rmap walks, but it can be
directly caluclated outside of the walks. Remove the 'folio_sz' field
from 'damon_pa_access_chk_result struct' and calculate the size directly
from outside of the walks.
