SubjectRe: [PATCH bpf-next 1/2] bpf: Add a bpf_kallsyms_lookup helper
Hi Florent,

Thank you for the patch! Perhaps something to improve:

[auto build test WARNING on bpf-next/master]

base: master
config: i386-randconfig-s002-20201127 (attached as .config)
compiler: gcc-9 (Debian 9.3.0-15) 9.3.0
# apt-get install sparse
# sparse version: v0.6.3-151-g540c2c4b-dirty
git remote add linux-review
git fetch --no-tags linux-review Florent-Revest/bpf-Add-a-bpf_kallsyms_lookup-helper/20201127-010044
git checkout 5ddc01183fb25936551dbf6d0b875f8d75dccdf3
# save the attached .config to linux build tree
make W=1 C=1 CF='-fdiagnostic-prefix -D__CHECK_ENDIAN__' ARCH=i386

If you fix the issue, kindly add following tag as appropriate
Reported-by: kernel test robot <>

"sparse warnings: (new ones prefixed by >>)"
>> kernel/trace/bpf_trace.c:1291:29: sparse: sparse: symbol 'bpf_kallsyms_lookup_proto' was not declared. Should it be static?

Please review and possibly fold the followup patch.
