Hi,
later in the 4.10 release cycle it turned out that b4536f0c829c ("mm,
memcg: fix the active list aging for lowmem requests when memcg is
enabled") was not sufficient to fully close the regression introduced by
f8d1a31163fc ("mm: consider whether to decivate based on eligible zones
inactive ratio") [1]. mmotm tree behaved properly and it turned out the
Linus tree was missing 71ab6cfe88dc ("mm, vmscan: consider eligible
zones in get_scan_count") merged in 4.11 merge window. The patch heavily
depends on 4a9494a3d827 ("mm, vmscan: cleanup lru size claculations")
which has been backported as well (patch 1).
Please add these two to 4.9+ trees (they should apply to 4.10 as they
are). 4.8 tree will need them as well but I do not see this stable tree
being maintained.
