From: Baoquan He

When tried to review below patchset from Joonsoo, I found out there's
some space to improve about lowmem_reserve and /proc/zoneinfo printing.
So made this patchset to do it.

[PATCH v3 0/2] integrate classzone_idx and high_zoneidx
http://lkml.kernel.org/r/1584693135-4396-1-git-send-email-iamjoonsoo.kim@xxxxxxx

Baoquan He (5):
mm/page_alloc.c: only tune sysctl_lowmem_reserve_ratio value once when
changing it
mm/page_alloc.c: clear out zone->lowmem_reserve[] if the zone is empty
mm/vmstat.c: do not show lowmem reserve protection information of
empty zone
mm/vmstat.c: move the per-node stats to the front of /proc/zoneinfo
mm/vmstat.c: remove the useless code

mm/page_alloc.c | 13 +++++++++++--
