Mykyta Yatsenko says: ==================== libbpf: stringify error codes in log messages From: Mykyta Yatsenko <yatsenko@meta.com> Libbpf may report error in 2 ways: 1. Numeric errno 2. Errno's text representation, returned by strerror Both ways may be confusing for users: numeric code requires people to know how to find its meaning and strerror may be too generic and unclear. These patches modify libbpf error reporting by swapping numeric codes and strerror with the standard short error name, for example: "failed to attach: -22" becomes "failed to attach: -EINVAL". ==================== Link: https://patch.msgid.link/20241111212919.368971-1-mykyta.yatsenko5@gmail.com Signed-off-by: Andrii Nakryiko <andrii@kernel.org>
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.
