Hi everybody!

Recently, there are some efforts to handle system memory pressure.

1) low memory notification - [1]
2) fallocate(VOLATILE) - [2]
3) fadvise(NOREUSE) - [3]

For them, I would like to add new LRU list, aka "Ereclaimable" which
is opposite of "unevictable".
Reclaimable LRU list includes_easy_  reclaimable pages.
For example, easy reclaimable pages are following as.

1. invalidated but remained LRU list.
2. pageout pages for reclaim(PG_reclaim pages)
3. fadvise(NOREUSE)
4. fallocate(VOLATILE)

Their pages shouldn't stir normal LRU list and compaction might not
migrate them, even.

What about other things moving memory like CMA ?

Sorry for not being able to understand your point.
Can you elaborate a bit more?
