For those of us not familiar with what CO-RE is, this doesn't help. I assume the [0] was a reference to something that explained it, but that isn't included.the reference [0] is link to a blog post which explains the eBPF CO-RE concept; I have added this link as a reference below.quoted
What is "BTF information"? Google suggests it's something to do with the British Thyroid Foundation. Please don't use three letter abbreviations unless they are widely understood, or if you wish to, please ensure that you explain them. TLAs otherwise are an exclusion mechanism.quoted
What is this "vmlinux.h" ? It isn't something that the kernel provides afaics. It doesn't seem to be present on my existing x86 Debian system. I've seen it on Fedora systems in the dim and distant past. Where do you think it comes from? Where are you finding it?The blog post [0] provides description and context for the references and abbreviations used, but in the future I will be sure to avoid using abbreviations unless they are commonly understood.

Okay, you've addressed one point I raised, but you have not addressed any of the questions I raised. I'll take this thread as just noise on the mailing list since it seems to contain nothing of any relevance to the Linux kernel, and no one seems willing to explain why they think it is relevant. Thanks. -- RMK's Patch system: https://www.armlinux.org.uk/developer/patches/ FTTP is here! 40Mbps down 10Mbps up.
