From: "Mike Rapoport (Microsoft)" Lorenzo says: static const struct vm_uffd_ops *vma_uffd_ops(struct vm_area_struct *vma) { if (vma_is_anonymous(vma)) return &anon_uffd_ops; return vma->vm_ops ? vma->vm_ops->uffd_ops : NULL; } This is doing a redundant check _and_ making life confusing, as if !vma->vm_ops is a condition that can be reached there, it can't, as vma_is_anonymous() is literally a !vma->vm_ops check :) Remove the redundant check.
