Re: [PATCH v1 02/11] mm: convert track_pfn_insert() to pfnmap_sanitize_pgprot()
From: David Hildenbrand

- 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.
