Buried in http://www.skynet.ie/~mel/projects/vm/guide/html/understand/node70.html#SECTION001533000000000000000 is "An anonymous page may have associated buffers if it is backed by a swap file." The reason being that the page will need to be written out in block-sized chunks. Once written out, the page->buffers will be null again and it'll be cleared out the normal way via the swap cache when all processes have unmapped the page -- Mel Gorman http://www.csn.ul.ie/~mel -- Kernelnewbies: Help each other learn about the Linux kernel.
