Matthew Wilcox (Oracle) 7e8347413e mm: correct page_mapped_in_vma() for large folios 
Patch series "Unify vma_address and vma_pgoff_address".

The current vma_address() pretends that the ambiguity between head & tail
page is an advantage.  If you pass a head page to vma_address(), it will
operate on all pages in the folio, while if you pass a tail page, it will
operate on a single page.  That's not what any of the callers actually
want, so first convert all callers to use vma_pgoff_address() and then
rename vma_pgoff_address() to vma_address().


This patch (of 3):

If 'page' is the first page of a large folio then vma_address() will scan
for any page in the entire folio.  This can lead to page_mapped_in_vma()
returning true if some of the tail pages are mapped and the head page is
not.  This could lead to memory failure choosing to kill a task
unnecessarily.
