Change value type in progs/tag.c to a typedef with a btf_decl_tag.
With `bpftool btf dump file tag.o`, we have
...
[14] TYPEDEF 'value_t' type_id=17
[15] DECL_TAG 'tag1' type_id=14 component_idx=-1
[16] DECL_TAG 'tag2' type_id=14 component_idx=-1
[17] STRUCT '(anon)' size=8 vlen=2
'a' type_id=2 bits_offset=0
'b' type_id=2 bits_offset=32
...
The btf_tag selftest also succeeded:
$ ./test_progs -t tag
#21 btf_tag:OK

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.
