Seems this patch is built on top of the per-CPU/thread/read/write monitoring
patch series [1].  We made a plan [2] to use another user interface, though.
The plan is, making the interface ready for page table accessed bits based
monitoring by LPC'26 (milestone 1), and implementing the perf event based
monitoring on top of it, by LSFMMBPF'27 (milestone 2).

So the eventual damo part change for supporting perf event based monitoring
will be quite different from this series.  I guess you are sharing this series
not because you aiming to merge it as is right now, but just for sharing the
code with other stakeholders like Ravis, not me?  If I'm not wrong, I will skip
this series for now, to focus on the milestone 1.

Please let me know if you want more of my feedback.
