I see, and I'd like to suggest you to separate that series
from this "uprobe" series. For upstream merge, indeed, we
need a consumer of the uprobe. However, it should be as simple
as possible, so that we can focus on reviewing uprobe itself.

Interesting:) Could you tell us what the plan will introduce?
How will it be connected? how will we use it?
Thank you,
