    Actually for every kobj_type structure, not for every kobject. Doing a
    quick scan through the kernel I found 25 kobj_type decelerations so that
    would add up to 100 bytes only. And that could be made a byte or flags
    field.

    I wasn't sure if it was possible to create a subsystem that wasn't a
    part of the sysfs tree that contained kobjects that were. Looking
    trough the code again it looks like it is so I'll use the hotplug filter
    as you suggest.
