BTF type tags and decl tags now may have info->kflag set to 1,
changing the semantics of the tag.
Change BTF verification to permit BTF that makes use of this feature:
* remove kflag check in btf_decl_tag_check_meta(), as both values
are valid
* allow kflag to be set for BTF_KIND_TYPE_TAG type in
btf_ref_type_check_meta()
Make sure kind_flag is NOT set when checking for specific BTF tags,
such as "kptr", "user" etc.
Modify a selftest checking for kflag in decl_tag accordingly.

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.
