mainlining shenanigans
c93cc69004
Add new `btf dump` sub-command to bpftool. It allows to dump
human-readable low-level BTF types representation of BTF types. BTF can
be retrieved from few different sources:
- from BTF object by ID;
- from PROG, if it has associated BTF;
- from MAP, if it has associated BTF data; it's possible to narrow
down types to either key type, value type, both, or all BTF types;
- from ELF file (.BTF section).
Output format mostly follows BPF verifier log format with few notable
exceptions:
- all the type/field/param/etc names are enclosed in single quotes to
allow easier grepping and to stand out a little bit more;
- FUNC_PROTO output follows STRUCT/UNION/ENUM format of having one
line per each argument; this is more uniform and allows easy
grepping, as opposed to succinct, but inconvenient format that BPF
verifier log is using.

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.
