| Subject | [PATCH] mm: add per-zone lru list stat -fix |
| Message-ID | <rYIuR-1Id-9@gated-at.bofh.it> |
This patch renames the zone LRU stats as printed in /proc/vmstat to avoid
confusion. This keeps both the node and zone stats which normally will be
redundant but should always be roughly in sync.
This is a fix to the mmotm patch mm-add-per-zone-lru-list-stat.patch

Acked-by: Minchan Kim <minchan@kernel.org> Thanks.
