Hello,

this is v2 of the series introducing devfs_create_partitions. With the
new syntax creating partitions is easier to parse for humans, it has
support to create partitions without holes inbetween without the need to
explicitly calculate the offsets and the code generated for the callers
is smaller.

I compared the size of arch/arm/boards/a9m2410/a9m2410.o with and
without the series with the kernel's bloat-o-meter, with the following
result:

add/remove: 1/0 grow/shrink: 0/1 up/down: 84/-104 (-20)
function                                     old     new   delta
a9m2410_nand0_partitions                       -      84     +84
a9m2410_devices_init                         296     192    -104

(Well, the size advantage is a *bit* relativized by the growth of fs/devfs-core.o:

add/remove: 3/0 grow/shrink: 0/1 up/down: 508/-124 (384)
function                                     old     new   delta
__devfs_add_partition.part                     -     376    +376
devfs_create_partitions                        -     128    +128
new                                            -       4      +4
devfs_add_partition                          296     172    -124

Don't know what "new" is above.)

Compared to (implicit) v1 of this series I dropped the compound
literals and used named static arrays instead as wished by Sebastian
Hesselbarth and Sascha Hauer.

Best regards
Uwe
