The latter half of this description is a bit confusing. Why would the value differ from (vma->vm_start >> PAGE_SHIFT)? (because it's file backed?) It sounds like this value can change in response to an event, which makes me thing a reader could see two values across two calls? Apologies if i'm fundamentally misunderstanding something. ~Gregory
