Not only is this interesting, but the efficiency of anonymous page
reclamation also frequently affects the performance of our products.
In our flame graphs, we can see that many anonymous page reverse mapping

Therefore, please continue your work—I’m really looking forward to the

Additionally, if there’s anything I can do to help, I’d be happy to
participate.
Thanks.
