Hi Song,

I love your patch! Perhaps something to improve:

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

url:    https://github.com/0day-ci/linux/commits/Song-Liu/introduce-BPF_PROG_TYPE_USER/20200801-165208
base:   https://git.kernel.org/pub/scm/linux/kernel/git/bpf/bpf-next.git master
config: x86_64-randconfig-s031-20200806 (attached as .config)
compiler: gcc-9 (Debian 9.3.0-15) 9.3.0
reproduce:
        # apt-get install sparse
        # sparse version: v0.6.2-117-g8c7aee71-dirty
        # save the attached .config to linux build tree
        make W=1 C=1 CF='-fdiagnostic-prefix -D__CHECK_ENDIAN__' ARCH=x86_64 

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


sparse warnings: (new ones prefixed by >>)

>> kernel/trace/bpf_trace.c:1855:31: sparse: sparse: symbol 'user_verifier_ops' was not declared. Should it be static?
>> kernel/trace/bpf_trace.c:1860:27: sparse: sparse: symbol 'user_prog_ops' was not declared. Should it be static?

Please review and possibly fold the followup patch.
