bpf: selftests: Do not use generated kfunc prototypes for arena progs
When selftests are built with a new enough clang, the arena selftests opt-in to use LLVM address_space attribute annotations for arena pointers. These annotations are not emitted by kfunc prototype generation. This causes compilation errors when clang sees conflicting prototypes. Fix by opting arena selftests out of using generated kfunc prototypes. Fixes: 770abbb5a25a ("bpftool: Support dumping kfunc prototypes from BTF") Reported-by: kernel test robot <lkp@intel.com> Closes: https://lore.kernel.org/r/202406131810.c1B8hTm8-lkp@intel.com/ Signed-off-by: Daniel Xu <dxu@dxuuu.xyz> Link: https://lore.kernel.org/r/fc59a617439ceea9ad8dfbb4786843c2169496ae.1718295425.git.dxu@dxuuu.xyz Signed-off-by: Alexei Starovoitov <ast@kernel.org>
