[PATCH v3 01/16] mm: use put_page to free page instead of putback_lru_page
...hat we just potentially freed.
Yes, while I read the code, I had same question. I think the releasing
refcount is for get_any_page.
Naoya, could you answer above two questions?
Thanks.

[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.
