I'm fine with tweaking the elevators to know about low-latency seeks.
But please stop describing it as "a blatant layering violation".
It's nothing of the sort.  It's setting a default at a point where we
find out the information which would guide us.

I haven't looked into doing this in udev yet; I've got caught up in
another project.  In any case, it seems like there's no role for udev
any more, so I'll probably not spend any more time on this unless there's
some need.
