Unfortunately, I don't think that this proposal, alternative (3) "The
custom zonelist option", handles the fake numa node case that Andrew is
raising with the desired performance. For Andrew's particular load, it
would still have long zonelists that had to be scanned before finding a
node with free memory.

there is a link to my original patch:
