I have put them into st.c for the moment which should fix the compile

Perhaps at the moment but what if we considered keeping stats for all
the partitions on a disk individually?  Solaris does this and I think
it would be a nice idea to implement for us - at the moment you can
only tell which _disk_ is busy, sometimes it can be very helpful to
know that /var is being thrashed by something...

True, but it would be for attach (or just have a different attach) due
to all the extra information associated with a disk attach.

I think it would be misleading to keep the current naming, if these
are to be generic routine then they should have more generic names to
reflect that.
