Initially in commit69b693f0ae("bpf: btf: Introduce BPF Type Format (BTF)") the function 'btf_name_offset_valid' was introduced as static function it was later on changed to a non-static one, and then finally in commit23127b33ec("bpf: Create a new btf_name_by_offset() for non type name use case") the function prototype was removed. Revert back to original implementation and make the function static. Remove warning triggered with W=1: kernel/bpf/btf.c:470:6: warning: no previous prototype for 'btf_name_offset_valid' [-Wmissing-prototypes] Fixes:23127b33ec("bpf: Create a new btf_name_by_offset() for non type name use case") Signed-off-by: Mathieu Malaterre <malat@debian.org> Acked-by: Martin KaFai Lau <kafai@fb.com> Signed-off-by: Daniel Borkmann <daniel@iogearbox.net>
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.
