If you are going to resubmit the series.

Documentation/process/coding-style.rst
  1140 21) Conditional Compilation
  1141 ---------------------------
....
  1156 If you have a function or variable which may potentially go unused in a
  1157 particular configuration, and the compiler would warn about its definition
  1158 going unused, mark the definition as __maybe_unused rather than wrapping it in
  1159 a preprocessor conditional.  (However, if a function or variable *always* goes
  1160 unused, delete it.)

Thanks
