    A lot of the (driver) users want a wallclock based timeout. For that,
    miliseconds is a more obvious API with less chance to get the jiffies/HZ
    conversion wrong by the driver writer.

    It's not about precision, it's about making the new API (which is
    intended to be a simplification already due to sucking in the state
    setting) match the intent closer.
