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
