SubjectRe: [PATCH v2 bpf-next 10/13] bpf: Add instructions for atomic[64]_[fetch_]sub
Hi Brendan,

Thank you for the patch! Perhaps something to improve:

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

base: master
config: i386-randconfig-s001-20201127 (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 Brendan-Jackman/Atomics-for-eBPF/20201128-020057
git checkout 8b1823a5cf4569c72046175d217e3e2ad68c6a05
# 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/bpf/disasm.c:83:12: sparse: sparse: symbol 'bpf_atomic_alu_string' was not declared. Should it be static?

Please review and possibly fold the followup patch.
