  SVN rev 219401 on 2011-03-08 17:27:36Z by jh
  
  MFC r201773:
  
  - Change the type of size_max to u_quad_t because its value is converted
    with vfs_scanopt(9) using the "%qu" format string.
  - Limit the maximum value of size_max to (SIZE_MAX - PAGE_SIZE) to
    prevent overflow in howmany() macro.
  
  PR:             kern/141194
  
  MFC r202187:
  
  - Fix some style bugs in tmpfs_mount().
  - Remove a stale comment about tmpfs_mem_info() 'total' argument.
  
  MFC r202708:
  
  - Change the type of nodes_max to u_int and use "%u" format string to
    convert its value.
  - Set default tm_nodes_max to min(pages + 3, UINT32_MAX). It's more
    reasonable than the old four nodes per page (with page size 4096) because
    non-empty regular files always use at least one page. This fixes possible
    overflow in the calculation.
  - Don't allow more than tm_nodes_max nodes allocated in tmpfs_alloc_node().
