Subject: mm/damon/vaddr: record appropriate folio size when the access is not found
Date: Mon, 9 Jan 2023 21:33:32 +0000

DAMON virtual address spaces monitoring operations set doesn't set folio
size of the access checked address if access is not found.  It could
result in unnecessary and inefficient repeated check.  Appropriately set
the size regardless of access check result.
