Care to explain why?

Following is an explanation why the contrary is probably true:

1) We have lots of precedents in existing code:

dmvo@...her:~/Projects/misc/linux$ git-grep 'extern void' include | wc -l
5523
dmvo@...her:~/Projects/misc/linux$

2) Linus' Coding style does not mandate what you requested.

3) The checkpatch.pl did not complain at this particular patch.

Thanks,

Dmitri
