(related to bpf itself not modprobe subject)
Hi Chris,
I just want to point out that the tool 'bpftool', is currently the
dominating tool for eBPF introspection. And the 'bps' tool you mention
seems to have gained less (open source) traction.
The bpftool is part of the kernel git-tree: tools/bpf/bpftool
https://github.com/torvalds/linux/blob/master/tools/bpf/bpftool/
And it even have bash-completion and man-pages in RST format so they
even render nicely when viewed via github:
https://github.com/torvalds/linux/blob/master/tools/bpf/bpftool/Documentation/bpftool.rst
https://github.com/torvalds/linux/blob/master/tools/bpf/bpftool/Documentation/bpftool-prog.rst
https://github.com/torvalds/linux/blob/master/tools/bpf/bpftool/Documentation/bpftool-map.rst
