*
* The following other idents are available
*
* "Proprietary" [Non free products]
*
* Both "GPL v2" and "GPL" (the latter also in dual licensed strings) are
* merely stating that the module is licensed under the GPL v2, but are not
* 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
