6. Perhaps don't use the LRU pagevecs for large pages. It limits the

I think that makes sense. Being large already amortizes the cost per base
page much more than pagevecs do (512 vs ~22 pages?).
We try to do this already, don't we? Any spefic case where we have THPs on
pagevecs?
For example like this?
__do_huge_pmd_anonymous_page
lru_cache_add_active_or_unevictable
lru_cache_add
