Re: [PATCH 5.4 0/8] BPF backports for CVE-2021-29155

Sure. I have a 4.14 one coming up too, but that one was just a little harder, and it also corrects a previous backport error that was made (correction was already acked), and picks some other commits to get selftests clean. So I'll probably send it to just bpf@ first.

Others will have to take care of 4.19 or older kernels, though, just flagging that I have done the 4.14 backport for these.
