Bah, checkpatch should be considered harmful when run on code that
has been around for years. It's a good guide for new code, but...

$ git grep extern fs/xfs/xfs*h |wc -l
345
$ git grep extern include/linux/*h |wc -l
6878
$

.... and the rule of "consistent with existing coding style" when
adding code to existing files generally trumps any "style errors"
that checkpatch might warn about.

Anyway, it's a cleanup patch to begin with, and there's only a few
of them, so it's not worth complaining about.
