Hello,
This patchset is follow-up of the problem reported and discussed two years ago [1, 2]. The problem this patchset solves is related to the classzone_idx on the NUMA system. It causes a problem when the lowmem reserve protection exists for some zones on a node that do not exist on other nodes.
This problem is reported two years ago, and, at that time, the solution got general agreements [2]. But, due to my laziness, it's not upstreamed. Now, I tried again. This patchset is based on next-20200416 git tree.
Thanks.
Changes on v5 - rebase onto the next-20200416 - add review tags
Changes on v4 - improve the commit message again
Changes on v3 - improve the commit message - remove useless accessor, ac_classzone_idx()
