Bug 2010428

no longer needed in 9.0, we have libbpf on kernel version 5.14.0-13.el9,
and there was no libbpf change since

Build is ready:

https://brewweb.engineering.redhat.com/brew/buildinfo?buildID=2063365

Currently running gating, there may be some problems but it should be ready for testing.

There appears to be a new feature however? Can you confirm it is okay without fully compiling like the following?
