When building bpf selftests like
make -C tools/testing/selftests/bpf -j20
I hit the following errors:
...

I am using:
-bash-4.4$ rst2man --version
rst2man (Docutils 0.11 [repository], Python 2.7.5, on linux2)
-bash-4.4$
The Makefile generated final .rst file (e.g., bpftool-cgroup.rst) looks like
...

The rst2man generated .8 file looks like

Looks like that particular version of rst2man prefers to have actual new line
instead of \n.
Since `echo -e` may not be available in some environment, let us use `printf`.
Format string "%b" is used for `printf` to ensure all escape characters are
interpretted properly.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
