-Although, roughly, 8 KB code is added in total, page_alloc.o increase by
-520 bytes and less than half of it is in hotpath. Building the kernel with
-page owner and turning it on if needed would be great option to debug

+Although enabling page owner increases kernel size by several kilobytes,

 There is one notice that is caused by implementation detail. page owner
 stores information into the memory from struct page extension. This memory
