So I'm just watching from the sidelines here, but I do feel the need to
point out that Kris appears to be trying to follow the previous feedback
he got from Alexei, where creating tools/dtrace is exactly what he was
told to do:
https://urldefense.proofpoint.com/v2/url?u=https-3A__lwn.net_ml_netdev_20190521175617.ipry6ue7o24a2e6n-40ast-2Dmbp.dhcp.thefacebook.com_&d=DwIDAg&c=RoP1YumCXCgaWHvlZYR8PZh8Bv7qIrMUB65eapI_JnE&r=TH500uwHRHLHqjhgluCyxMsbZEewvpf7ynuq0G-WrEk&m=nfIzLl36XfzUDFFM802KBQhhwh33nQjHuMS_ZQWE3hM&s=Ukw4knO0deTdli0wTNq8Hd6WJbs8PsCm5u9Tv8ddazU&e=
Now he's being told the exact opposite. Not the best experience for
somebody who is trying to make the kernel better.
There are still people interested in DTrace out there. How would you
recommend that Kris proceed at this point?
Thanks,
jon
