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-20200317 git tree. Thanks. Changes on v4 - improve the commit message again Changes on v3 - improve the commit message - remove useless accessor, ac_classzone_idx() [1]: http://lkml.kernel.org/r/20180102063528.GG30397@yexl-desktop [2]: http://lkml.kernel.org/r/1525408246-14768-1-git-send-email-iamjoonsoo.kim@lge.com Joonsoo Kim (2): mm/page_alloc: use ac->high_zoneidx for classzone_idx mm/page_alloc: integrate classzone_idx and high_zoneidx include/linux/compaction.h | 9 ++-- include/linux/mmzone.h | 12 ++--- include/trace/events/compaction.h | 22 ++++---- include/trace/events/vmscan.h | 14 +++-- mm/compaction.c | 64 +++++++++++------------ mm/internal.h | 21 +++++--- mm/memory_hotplug.c | 6 +-- mm/oom_kill.c | 4 +- mm/page_alloc.c | 60 +++++++++++----------- mm/slab.c | 4 +- mm/slub.c | 4 +- mm/vmscan.c | 105 ++++++++++++++++++++------------------ 12 files changed, 175 insertions(+), 150 deletions(-) -- 2.7.4
