Re: [RFC PATCH 0/2] mm: multi-gen LRU: per-process heatmaps

Hi Yuanchu,

I'm working on observability and the programmable page generation policy of MGLRU based on eBPF, using a similar approach to yours. 
I'd like to know if there is any related work, such as the application of eBPF in MGLRU? 
Also, this RFC provides a user space interface to call run_aging(), which is called periodically in the demo. 
Do you plan to optimize this, perhaps by calling run_aging() based on page access observation results?

Thanks!
