    Not an enhancement. Uwe's current approach causes regressions
    in terms of kernel runtime footprint. That is, pages will newly
    be made to sit around doing *nothing* forever, when they could
    have been used to get Real Work done. And, pre-patches, they
    would have been getting Real Work done.

    If it weren't a regression I wouldn't have objected.

    A few years back, I measured the impact of having probe() and
    friends in a section -- init{,data} vs devinit{,data} -- that gets
    removed. Most drivers were in the 1K-2K range. $SUBJECT was
    larger than most, but there were some with even more discardable
    init logic.

    All that adds up. There's no point to commiting patches that
    do things wrong *and* waste space, then need to fix things up
    again later when it's easy to do it right in the first place.
