libbpf-devel rpm uapi headers

Show all headers | View raw

hi,
we'd like to have bcc linked with libbpf instead of the
github submodule, initial change is discussed in here:
  https://github.com/iovisor/bcc/pull/2535

In order to do that, we need to have access to uapi headers
compatible with libbpf rpm, bcc is attaching and using them
during compilation.

I added them in the fedora spec below (not submitted yet),
so libbpf would carry those headers.

Thoughts? thanks,
jirka
