Well, this is a stable kernel, and the patch does adversely
affect overall throughput.

There are two changes to the elevator in that patch. One
is a modest speedup for all workloads which, frankly, I'm
inclined to drop. The other is the part which gives the
improved responsiveness.

Being a cautious chap, I think I'll submit that patch, with
the default setting to "off", so there is no change to default
kernel behaviour. Then people can run `elvtune -b' to enable it.
