Subject: mm/memory: Use vma_lookup() instead of find_vma_intersection()
X-Git-Url: https://www.infradead.org/git/?a=commitdiff_plain;h=21a4d69e1780610bafce353e730c5a51736802c3;p=users%2Fjedix%2Flinux-maple.git

mm/memory: Use vma_lookup() instead of find_vma_intersection()

Use the new vma_lookup() call for abstraction & code readability.
