Series bpf: detect build errors for man pages for bpftool and eBPF helpers | expand

Commit Message

Quentin Monnet Sept. 7, 2020, 4:40 p.m. UTC 
To build man pages for bpftool (and for eBPF helper functions), rst2man
can log different levels of information. Let's make it log all levels
to keep the RST files clean.

Doing so, rst2man complains about double colons, used for literal
blocks, that look like underlines for section titles. Let's add the
necessary blank lines.
