[PATCH v3 04/16] mm/balloon: use general movable page feature into balloon
...patch 02/16? And this patch should be just removing the
balloon-specific check? Otherwise it seems like between patches 02 and
04, other kinds of PageMovable pages were unnecessarily/wrongly routed
through putback_lru_page()?

[PATCH v3 00/16] Support non-lru page migration
Recently, I got many reports about perfermance degradation
in embedded system(Android mobile phone, webOS TV and so on)
and failed to fork easily.
The problem was fragmentation caused by zram and GPU driver
pages. Their pages cannot be migrated so compaction cannot
work well, either so reclaimer ends up shrinking all of working
set pages. It made system very slow and even to fail to fork
easily.
