Why no stack folding with libbpf offcputime?

libbpf tools are meant to be a replacement for BCC tools, however offcputime lacks the stack folding argument -f.

What is the recommended way to use the libbpf version of offcputime to generate a flame graph similar to how one does it with the BCC version.

FWIW, I see you have a PR that someone submitted over a year ago to add this option.

The issue names the libbpf offcputime tool, the BCC version's -f option, and an older proposed pull request, but no files or tests. First inspect the existing pull request and current offcputime usage; completion would be either a documented flame-graph workflow or equivalent stack-folding support with verification.
