But actually I would expect pte_pfn() to return max_mapnr because the mapped page is not a local page. And that should cause vm_normal_page() to return NULL always, regardless of whether you assert VM_PFNMAP. Is gntdev being used to grant-and-map local pages in the test that causes the crash? -- Keir _______________________________________________ Virtualization mailing list Virtualization@lists.linux-foundation.org https://lists.linux-foundation.org/mailman/listinfo/virtualization
