And looking at all the discussions and problems that already happened
during the development of this series, I think we should rather look
into how clean free page hinting might solve the same problem.
I'm not sure I follow the logic. We found that neat tricks
especially re-using the max order free page for reporting.
Let me rephrase: history of this series showed that this is some really
complicated stuff. I am asking if this complexity is actually necessary.
No question that we had a very valuable outcome so far (that especially
is also relevant for other projects like Nitesh's proposal - talking
about virtio requests and locking).

If it can't be solved using free page hinting, fair enough.
I suspect Nitesh will need to find a way not to have mm code
call out to random drivers or subsystems before that code
is acceptable.
