Section number and name:

Chapter 27. Analyzing system performance with BPF Compiler Collection
Chapter 36. Analyzing system performance with BPF Compiler Collection 

Describe the issue:

The documentation refers to BPF several times but does not expand the acronym or provide any links to other documentation on BPF (Berkeley Packet Filter).
The RHEL 9.2 release notes do expand the acronym: https://docs.redhat.com/en/documentation/red_hat_enterprise_linux/9/html/9.2_release_notes/available_bpf_features

The RHEL 9 docs does have the expanded acronym in section 9.9 Installing PCP bpftrace but I believe this should be expanded in every chapter on first use.

Impact of this issue:

Using acronyms without expanding them on first use per chapter means that users have to go searching for the meaning to understand the documentation.

Not linking to other documents on the topic reduces the value users get from our existing documentation.
