Can multiple BPF programs use same per-cpu perf ring buffer?
Imagine I have a per-cpu perf ring buffer for all my cpus.
Now I have two eBPF programs.
In both these eBPF programs I do bpf_update_elem(myFD, &cpunumberkey,
Will this mean that multiple eBPF programs will be able to write their
data into a single buffer (of course associated with cpu).
This would be amazing if it is truly possible. It seems like it should
I have not tried yet.
