The core idea of this patch set is to enable users to perceive the number of any
pages merged by KSM, regardless of whether use_zero_page switch has been turned
on, so that users can know how much free memory increase is really due to their
madvise(MERGEABLE) actions. But the problem is, when enabling use_zero_pages,
all empty pages will be merged with kernel zero pages instead of with each
other as use_zero_pages is disabled, and then these zero-pages are no longer
monitored by KSM.
We appear to have some outstanding activity on this quite old patchset.
From my notes:
- An unresponded-to question from Claudia:

- Hoping for overall review from David
I already shared some feedback in [1]. I think we should try to simplify
this handling, as proposed in that mail. Still waiting for a reply.
