Hello,
when i try to compile my kernel extension as modul, i get some undefined
references. But a look in System.map shows, that the relevant symbols
are defined in the main kernel. Why then those undefined references ?
Any hint is appreciated!
bye
Josef

Symbol must be exported to be available for modules, just being listed
in System.map isn't enough.
Try adding EXPORT_SYMBOL(...) for those "undefined" references.
