hi Michal,

Thanks a lot for reminder!

Except a update on patch [PATCH v17 18/21] mm/lru: introduce the relock_page_lruvec function
from Alexander, the patchset is stable on 5.8.

Just on linux-next, there are changes on hpage_nr_pages -> thp_nr_pages func name change, and
lru_note_cost changes that they need a new update.
And I have another 3 more patches, following this patchset which do clean up and optimzing.

Is it worth for a new patchset? or let me just update here?

Thanks
Alex
