Sounds a good idea. I'll try it, too.

[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

[patch 0/6] [rfc] guest page hinting version 5
After way to many months here is the fifth version of the guest page
hinting patches. Compared to version four a few improvements have been
added:
- Avoid page_host_discards() calls outside of page-states.h
- The discard list is now implemented via the page_free_discarded
hook and architecture specific code.
- PG_state_change page flag has been replaced with architecture
