Subject: [PATCH 2/6] mm/damon/vaddr: support folio of neither HPAGE_PMD_SIZE nor PAGE_SIZE
Date: Mon,  9 Jan 2023 21:33:31 +0000	[thread overview]
Message-ID: <20230109213335.62525-3-sj@kernel.org> (raw)
In-Reply-To: <20230109213335.62525-1-sj@kernel.org>

DAMON virtual address space monitoring operations set treats folios
having non-HPAGE_PMD_SIZE size as having PAGE_SIZE size.  Use the exact
size of the folio.
