That's a good point and from what I can see it's correct with huge pages being
used (it means all processes see the same NUMA node assignment regardless of
access patterns).
That said, wouldn't that be too strong to impose a restriction that huge_pages
must be enabled?
Jakub, thanks for the new patch version! FWIW, I did not look closely to the
code yet (just did the minor changes already shared to have valid result with non
tiny shared buffer size). I'll look closely at the code for sure once we all agree
on the design part of it.
