Subject: mm: page->mapping folio->mapping should have the same offset
In commit 7b230db3b8d3 ("mm: Introduce struct folio"), folio is
introduced. This is a folio of page, so we need to make sure those
members of folio should be at the same offset in page.
The offset of mapping is not checked. This patch just adds it.
