No functional change.

This patch migrates module version support out of core code into
kernel/module/version.c. In addition simple code refactoring to
make this possible.

kernel/module/version.c:103:6: warning: symbol 'module_layout' was not
declared. Should it be static?

The function module_layout() does not appear to be used. So, I've decided
to remove it.

I'm not sure you can do that.

 From commit 8c8ef42aee8f ("module: include other structures in module 
version check") I understand that module_layout is there for some signature.

Ok.

Why don't leave this in main.c ?

Yes, struct 'symsearch' is not used outside of kernel/module/main.c.

inline is pointless for a non static function

This was an unfortunate oversight.

Same, not point for inline keyword here.

Agreed.
