Arnaldo, what is the latest news on this set?
I think you've looked at most of them over the last months and few patch
reorders were necessary. Is it all addressed ? All further work is
sadly blocked, because these core patches need to come in first.
I took another look today and to me patches 1-30 look good.
Thanks!

I asked Ingo if he had anything else to mention about changelog format
so that I could try pulling it directly, i.e. I need give it a last
look, and this is not a per-patchkit cost, its just fine tuning that
_should_ make processing subsequent patchkits faster, by pulling instead
of me going thru each patch.

But I disagree it "prevents further work", nobody has to wait for
everything to get upstream to do work, anyway, it will be processed.

I think Xia Kaixu's BPF read pmu patch series is waiting for this. 
Please have
a look at [1]. His kernel side patches has already collected by net-next,
and waiting for userside update.

However he is also waiting for net-next be merged, and currently we are 
the only
user of that feature :)
