Documentation: extend use case for EXPORT_SYMBOL_GPL()
Current documentation over use case for EXPORT_SYMBOL_GPL() only acknowledges functions which are "an internal implementation issue, and not really an interface". In practice these days though we have some maintainers taking on preferences to require all new functionality go in with EXPORT_SYMBOL_GPL(). A maintainer asking developers to use EXPORT_SYMBOL_GPL() for new functionality tends to be a well accepted and understood position that maintainers can take and typically requires the maintainers educating contributing developers on their own positions and requirements. Developers who submit code to maintainers not familiar with these preferences as optional for new functionality need explicit guidence though as existing documentation does not acknowledge this as a valid possibility. Without this being documented some maintainers are reluctant to accept new functionality with EXPORT_SYMBOL_GPL(). This extends the use case documentation for EXPORT_SYMBOL_GPL() to acknowledge acceptance for new functionality. Signed-off-by: Luis R.
