If I didn't explain it in detail so far, has been because of lack of
time. Plus nobody asked specific questions on the internals yet. And I
do my best to avoid writing books through email even if I fail at that
sometime.
I wanted do a few more code changes to make it faster first (like
badly needed THP migration).
For sure, I'll prepare some initial highlevel documentation on the
AutoNUMA algorithms for the MM summit (the resulting pdf I will
publish it of course), in addition to more benchmark data.
Thanks,
Andrea
