FWIW, I think Barry Song and Kairui Song would be good candidates for the maintainer role. Both of them have been contributing to MGLRU consistently and substantially. Barry is currently working on improving aging and fixing the swappiness-related issues, and Kairui is driving the MGLRU-FG optimization work. They have also been active in reviewing MGLRU patches, and their review comments are usually to the point and helpful. They have been looking after this code well, so I think they would be a good fit as maintainers. -- Best regards Ridong
