Hi Stephen,
A potential hotfix is here:
https://lore.kernel.org/bpf/d80c77cf-c570-4f3b-960f-bbd2d0316fac@linux.dev/
Needs acks/nacks.

All,
heads up. gmail doesn't like me :(
I see Steven's and Ihor's replies in lore, but nothing in my mailbox.
And Steven's reply was a couple hours ago.
Nothing in my spam either, and I was cc-ed directly!
So it's not mailing list delivery throttling.
Ouch.
If it looks like I'm ignoring your emails, it's not me. It's gmail fault.
