Having multiple unwinding libraries makes the perf code harder to understand and we have unused/untested code paths. Perf made BPF support an opt-out rather than opt-in feature. As libbpf has a libelf dependency, elfutils that provides libelf will also provide libdw. When libdw is present perf will use libdw unwinding rather than libunwind unwinding even if libunwind support is compiled in. Rather than have libunwind built into perf and never used, explicitly disable the support and make it opt-in.

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 reStructuredText 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.
