That bug is addressed later in the tree by "mm, vmscan: Update all zone
LRU sizes before updating memcg". Is the warning visible in the latest
mainline tree?

Yes that warning no longer show up in branch
"mm-vmscan-node-lru-follow-up-v2r1" HEAD.

Mainline kernel is also fine. I should have checked these,
sorry for the noise!

Regards,
Fengguang
