Subject: mm/damon/vaddr: rename 'damon_young_walk_private->page_sz' to 'folio_sz'
Date: Mon, 9 Jan 2023 21:33:30 +0000
Patch series "mm/damon/{v,p}addr: misc fixups for folio usage".
DAMON's monitoring operations set for the virtual and the physical address
spaces use folio now, but some code is not reflecting the fact. Further
cleanup the code for folio usage.
This patch (of 6):
DAMON's virtual address space monitoring operations set is using folio
now. Rename 'damon_pa_access_chk_result->page_sz' to reflect the fact.
