Hi Andrea, Peter,

I have a question on page refcounting in your NUMA
page migration code.

In Peter's case, I wonder why you introduce a new
MIGRATE_FAULT migration mode. If the normal page
migration / compaction logic can do without taking
an extra reference count, why does your code need it?

Hi Rik van Riel,

This is which part of codes? Why I can't find MIGRATE_FAULT in latest
v3.7-rc2?

It is in tip.git in the numa/core branch.
