It's up to the memory management folks to decide on this. -- Steve

Noted with thanks.

It would be really helpful to have more details on why we need those
trace points.

It is my understanding that you would like to have a more fine grained
numbers for the time duration of different parts of the reclaim process.
I can imagine this could be useful in some cases but is it useful enough
and for a wider variety of workloads? Is that worth a dedicated static
tracepoints? Why an add-hoc dynamic tracepoints or BPF for a very
special situation is not sufficient?

In other words, tell us more about the usecases and why is this
generally useful.

Thanks!
