NOTE: For some of the reported defects, checkpatch may be able to
      mechanically convert to the typical style using --fix or --fix-inplace.

Commit c348f8cf7393 ("selftests/bpf: Add tests to verify freeing the special fields when update hash and local storage maps") has style problems, please review.
