a nitpick, why did you replace this ALLOCATED_TAG assignment
with 2 'handle | OBJ_ALLOCATED_TAG'?

[PATCH v1 00/19] 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.
