   6 memrar.h
   7 --------
   8 1. This header exposes the driver's user space and kernel space
   9    interfaces.  It should be moved to <linux/rar/memrar.h>, or
  10    something along those lines, when this memrar driver is moved out
  11    of `staging'.
  12      a. It would be ideal if staging/rar_register/rar_register.h was
  13         moved to the same directory.
  14
  15 memrar_allocator.[ch]
  16 ---------------------
  17 1. Address potential fragmentation issues with the memrar_allocator.
  18
  19 2. Hide struct memrar_allocator details/fields.  They need not be
  20    exposed to the user.
  21      a. Forward declare struct memrar_allocator.
  22      b. Move all three struct definitions to `memrar_allocator.c'
  23         source file.
  24      c. Add a memrar_allocator_largest_free_area() function, or
  25         something like that to get access to the value of the struct
  26         memrar_allocator "largest_free_area" field.  This allows the
  27         struct memrar_allocator fields to be completely hidden from
  28         the user.  The memrar_handler code really only needs this for
  29         statistic gathering on-demand.
  30      d. Do the same for the "capacity" field as the
  31         "largest_free_area" field.
  32
  33 3. Move memrar_allocator.* to kernel `lib' directory since it is HW
  34    neutral.
  35      a. Alternatively, use lib/genalloc.c instead.
  36      b. A kernel port of Doug Lea's malloc() implementation may also
  37         be an option.
  38
  39 memrar_handler.c
  40 ----------------
  41 1. Split user space interface (ioctl code) from core/kernel code,
  42    e.g.:
  43      memrar_handler.c -> memrar_core.c, memrar_user.c
