After commitc698eaebdf("selftests/bpf: trace_helpers.c: Optimize kallsyms cache") trace_helpers.c now includes libbpf_internal.h, and thus can no longer use the u32 type (among others) since they are poison in libbpf_internal.h. Replace u32 with __u32 to fix the following error when building trace_helpers.c on powerpc: error: attempt to use poisoned "u32" Fixes:c698eaebdf("selftests/bpf: trace_helpers.c: Optimize kallsyms cache") Signed-off-by: Shung-Hsi Yu <shung-hsi.yu@suse.com> Acked-by: Jiri Olsa <jolsa@kernel.org> Link: https://lore.kernel.org/r/20240202095559.12900-1-shung-hsi.yu@suse.com Signed-off-by: Martin KaFai Lau <martin.lau@kernel.org>
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.
