Martin KaFai Lau says:
====================
The series allows the BPF loader to figure out the btf_key_id
and btf_value_id from a map's name by using BPF_ANNOTATE_KV_PAIR()
similarly as in iproute2 commit f823f36012fb ("bpf: implement
btf handling and map annotation").
It also removes the old 'typedef' way which requires two separate
typedefs (one for the key and one for the value).
By doing this, iproute2 and libbpf have one consistent way to
figure out the btf_key_type_id and btf_value_type_id for a map.
The first two patches are some prep/cleanup works. The last patch
introduces BPF_ANNOTATE_KV_PAIR.
v3:
- Replace some more *int*_t and u* usages with the
equivalent __[su]* in btf.c
v2:
- Fix the incorrect '&&' check on container_type
in bpf_map_find_btf_info().
- Expose the existing static btf_type_by_id() instead of
creating a new one.

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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
