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 
paths are among the hotspots.

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

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

Thanks.
