Thanks for the heads up.
I think we can hold off on this patchset for now. It has a notable
impact on MGLRU performance, and will still need a fair amount of
discussion, testing and revisions.
My apologies — I should have posted this version as an RFC.
Going forward, I’ll submit the whole series as RFCs, and only send
the formal patchset once we have a broadly agreed result.
Best,
Hui
