[PATCH] udev - create all partitions of blockdevice

Here is the first try to create all partitons of a blockdevice, since
removable media devices may need to acces the expected partition to
revalidate the media.

It uses the attribute syntax introduced with the last %s{file} patch.
I'm using this with my multi-slot-flash-card-reader:

  SYSFS{model}="USB Storage-SMC ", NAME{all_partitions}="smartmedia"
  SYSFS{model}="USB Storage-CFC ", NAME{all_partitions}="compactflash"
  SYSFS{model}="USB Storage-MSC ", NAME{all_partitions}="memorystick"
  SYSFS{model}="USB Storage-MMC ", NAME{all_partitions}="multimedia"

and I get:

  tree /udev/
  /udev/
  |-- memorystick
  |-- memorystick1
  |-- memorystick10
  |-- memorystick11
  |-- memorystick12
  |-- memorystick13
  |-- memorystick14
  |-- memorystick15
  |-- memorystick2
  |-- memorystick3
  |-- memorystick4
  |-- memorystick5
  |-- memorystick6
  |-- memorystick7
  |-- memorystick8
  |-- memorystick9
  |-- multimedia
  |-- multimedia1
  |-- multimedia10
  |-- multimedia11
  |-- multimedia12
  |-- multimedia13
  |-- multimedia14
  |-- multimedia15
  |-- multimedia2
  |-- multimedia3
  |-- multimedia4
  |-- multimedia5
  |-- multimedia6
  |-- multimedia7
  |-- multimedia8
  |-- multimedia9
  ...


If needed, we can make the number of partions to create
adjustable with the attribute?
