Oh, I already answered it in an earlier mail :)
  "these links don't exist with !SYSFS_DEPRECATED, because the
   class devices live in subdirectories, named after the class
   they come from, there is no namespace problem"

This is how a LUN looks now:
  tree /sys/devices/pci0000:00/0000:00:1d.7/usb5/5-1/5-1:1.0/host13/target13:0:0/13:0:0:0/
  /sys/devices/pci0000:00/0000:00:1d.7/usb5/5-1/5-1:1.0/host13/target13:0:0/13:0:0:0/
