I can see the 'CHECK' line when run checkpatch.pl on patch with '--strict' only. I think this can be a good reason that we should not add extern when add function declaration into header file.

Searching 'extern' under include can find so many functions with 'extern' adding. Do we have a explicit standard if we should add or remove 'exter' in function declaration? I have no objection to this patch, just want to make clear so that I can handle it w/o confusion. Thanks Baoquan
