    kernel - Double LRU dirty pages by default
    * The pageout daemon was supposed to double-LRU dirty pages in the inactive
      queue by default and it wasn't.  This was causing dirty tmpfs pages to
      have too much priority in the inactive queue.
      Theoretically since tmpfs now issues direct writes to backing store in
      low-memory situations, we should be able to allow its dirty pages to
      cycle normally in all other situations.
