Hmm... -f is to check a source file, not a patch... What did you try

OK, that's it. 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.

Good to know, thanks.

I didn't know checkpatch.pl can run on header file directly. Tried to
check patch with '--strict -f', the below info doesn't appear. But it
does give out below information when run on header file.

FWIW this is a warning condition for checkpatch:

$ ./scripts/checkpatch.pl --strict -f include/misc/ocxl.h

[...]

CHECK: extern prototypes should be avoided in .h files
#176: FILE: include/misc/ocxl.h:176:
+extern int ocxl_afu_irq_alloc(struct ocxl_context *ctx, int *irq_id);

[...]

For the OpenCAPI driver, we have settled on not having 'extern' on
functions.

I don't think I've seen a standard that supports or refutes this, but it
does not value add.

It works w or w/o extern when declare functions. 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.
