mainlining shenanigans
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.
