[ANN] bpf development stats for 6.4

[Stanislav Fomichev <sdf@google.com>]

Hi all,

Here is my attempt to apply Jakub's scripts to analyze mailing list activity.
See the following link for mode details and methodology:
https://lore.kernel.org/netdev/4d47c418-32d9-4d6a-9510-a6a927ebe61b@lunn.ch/T/#t

tl;dr: people/companies receive higher score when they participate in reviews
(vs only sending patches).

For now, I'm providing the numbers without any analysis.
