heh, maybe they read lkml and copied my ancient idea:
http://people.redhat.com/mingo/clearpage-patches/clearpage-2.3.18-J1
An earlier version had a 'zerod' (page zeroing kernel thread).
This was one of my more stupid ideas btw.
I think that with a dma engine it makes sense. We've got an extra
resource, why not utilize it in the background? Some workloads generate
a lot of demand for zero pages.
I agree that using the cpu to clear memory is not a good idea, it just
causes cache pollution.
