Subject: [PATCH bpf-next 0/9] bpf: remove bpf_load loader completely

Numerous refactoring that rewrites BPF programs written with bpf_load
to use the libbpf loader was finally completed, resulting in BPF
programs using bpf_load within the kernel being completely no longer
present.

This patchset refactors remaining bpf programs with libbpf and
completely removes bpf_load, an outdated bpf loader that is difficult
to keep up with the latest kernel BPF and causes confusion.

Daniel T. Lee (9):
