My point is that the patchset adds a lot of new code with no way in
which users can opt out.  Almost everyone gets a fatter kernel - how
many of those users will actually benefit from it?

If "not many" then shouldn't we be making it Kconfigurable?

Are there userspace tools which present this info to users or which
provide monitoring of some form?  Do major distros ship those tools? 
Do people use them?  etcetera.
