- track_pfn_insert(vma, &pgprot, pfn);+ if (pfnmap_sanitize_pgprot(pfn_t_to_pfn(pfn), PAGE_SIZE, &pgprot)) + return VM_FAULT_FALLBACK;Would "pgtable" leak if it fails? If it's PAGE_SIZE, IIUC it won't ever trigger, though.
Missed that comment. I can document that pgprot will only be touched if the function succeeds.
