Hi,
  When  read the source code of mm_types.h, i encounter _coding style_ code ,such like:
http://lxr.free-electrons.com/source/include/linux/mm_types.h#L346 in comments.
Why not try to fix it? Because it is trival? 
Actually, checkpatch.pl reports many errors and warnnings for it.
Only can i fix the coding style issue in staging?
Sorry for the noisy.
