Subject: [patch 0/2] Soft-dirty page tracker improvemens

Hi, as being reported by Andy, there are a couple of situations
when soft-dirty bit will be lost, in paricular when page we're
tracking is going to swap and when file page get reclaimed. In
this series both problems are aimed.

One more hardness which remains is the scenario when vma area
(which has soft-dirty bit set in appropriate pte entries) get
unmapped then new one mapped in-place. I'm working on it now
hope to provide a patch soon.

Thanks,
	Cyrill
