RAR Handler (memrar) Driver TODO Items
======================================
Maintainer: Eugene Epshteyn <eugene.epshteyn@intel.com>
memrar.h
--------
1. This header exposes the driver's user space and kernel space
interfaces. It should be moved to <linux/rar/memrar.h>, or
something along those lines, when this memrar driver is moved out
of `staging'.
a. It would be ideal if staging/rar_register/rar_register.h was
moved to the same directory.
memrar_allocator.[ch]
---------------------
1. Address potential fragmentation issues with the memrar_allocator.
2. Hide struct memrar_allocator details/fields. They need not be
exposed to the user.
a. Forward declare struct memrar_allocator.
b. Move all three struct definitions to `memrar_allocator.c'
source file.
c. Add a memrar_allocator_largest_free_area() function, or
something like that to get access to the value of the struct
memrar_allocator "largest_free_area" field. This allows the
struct memrar_allocator fields to be completely hidden from
the user. The memrar_handler code really only needs this for
statistic gathering on-demand.
d. Do the same for the "capacity" field as the
"largest_free_area" field.
3. Move memrar_allocator.* to kernel `lib' directory since it is HW
neutral.
a. Alternatively, use lib/genalloc.c instead.
b. A kernel port of Doug Lea's malloc() implementation may also
be an option.
memrar_handler.c
----------------
1. Split user space interface (ioctl code) from core/kernel code,
e.g.:
memrar_handler.c -> memrar_core.c, memrar_user.c
