    I am sorrry, that is complete bull*. sysfs also allows removing
    modules at an arbitrary time (and usually without annoying "waiting
    for refcount" at that)... You just seem to not understand how driver
    code works, thus the need of inventing your own schema.

    BTW, I am looking at the connector code ATM and I am just amazed at
    all wied refounting stuff that is going on there. what a single
    actomic_dec_and_test() call without checkng reurn vaue is supposed to
    do again?
