- * "Proprietary" [Non free products]
- *
- * Both "GPL v2" and "GPL" (the latter also in dual licensed strings) are

- * telling whether "GPL v2 only" or "GPL v2 or later". The reason why there
- * are two variants is a historic and failed attempt to convey more
- * information in the MODULE_LICENSE string. For module loading the
- * "only/or later" distinction is completely irrelevant and does neither
- * replace the proper license identifiers in the corresponding source file
- * nor amends them in any way. The sole purpose is to make the
- * 'Proprietary' flagging work and to refuse to bind symbols which are
- * exported with EXPORT_SYMBOL_GPL when a non free module is loaded.
- *
- * In the same way "BSD" is not a clear license information. It merely
- * states, that the module is licensed under one of the compatible BSD
- * license variants. The detailed and correct license information is again
- * to be found in the corresponding source files.
- *
- * There are dual licensed components, but when running with Linux it is the
- * GPL that is relevant so this is a non issue. Similarly LGPL linked with GPL
- * is a GPL combined work.
- *
- * This exists for several reasons
- * 1. So modinfo can show license info for users wanting to vet their setup
- * is free
- * 2. So the community can ignore bug reports including proprietary modules
- * 3. So vendors can do likewise based on their own policies
