Hi KP,

I love your patch! Perhaps something to improve:

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

base: master
config: i386-randconfig-s002-20201031 (attached as .config)
compiler: gcc-9 (Debian 9.3.0-15) 9.3.0
        # apt-get install sparse
        # sparse version: v0.6.3-68-g49c98aa3-dirty
        git remote add linux-review
        git fetch --no-tags linux-review KP-Singh/Implement-task_local_storage/20201028-010549
        git checkout 238fab90058acf3437ecf912b49b4fc11249fdef
        # 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:1032:29: sparse: sparse: symbol 'bpf_get_current_task_btf_proto' was not declared. Should it be static?

Please review and possibly fold the followup patch.
