[ Upstream commiteb04bbb608] This patch added name checking for the following types: . BTF_KIND_PTR, BTF_KIND_ARRAY, BTF_KIND_VOLATILE, BTF_KIND_CONST, BTF_KIND_RESTRICT: the name must be null . BTF_KIND_STRUCT, BTF_KIND_UNION: the struct/member name is either null or a valid identifier . BTF_KIND_ENUM: the enum type name is either null or a valid identifier; the enumerator name must be a valid identifier. . BTF_KIND_FWD: the name must be a valid identifier . BTF_KIND_TYPEDEF: the name must be a valid identifier For those places a valid name is required, the name must be a valid C identifier. This can be relaxed later if we found use cases for a different (non-C) frontend.

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.
