Subject: Three patches which collectively enable BTF debug info in BPF kernel
Date: Sat, 24 Feb 2024 20:09:09 -0500

[Message part 1 (text/plain, inline)]

This configuration causes /sys/kernel/btf/vmlinux to exist, which is
necessary for some eBPF programs (e.g. those that rely on the "BPF
CO-RE" feature; see
https://docs.kernel.org/bpf/libbpf/libbpf_overview.html for details).

The initial two patches introduce userland packages that enable building
the kernel with this configuration, and the third one changes the kernel
config.
