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.

The update to streamline libbpf error reporting intended to change all functions to return the errno as a negative return value if LIBBPF_STRICT_DIRECT_ERRS is set. However, if the flag is *not* set, the return value changes for the two functions that were already returning a negative errno unconditionally: bpf_link__unpin() and perf_buffer__poll(). This is a user-visible API change that breaks applications; so let's revert these two functions back to unconditionally returning a negative errno value.
