[PATCH v6 00/12] Support non-lru page migration
Recently, I got many reports about perfermance degradation in embedded

The problem was fragmentation caused by zram and GPU driver mainly.
With memory pressure, their pages were spread out all of pageblock and
it cannot be migrated with current compaction algorithm which supports
only LRU pages. In the end, compaction cannot
