Calling internal symbols _INTERNAL is confusing?
I think it's the combination of "INTERNAL" and "EXPORT" that seems
contradictory - "If it's internal, why are you exporting it?"
I think "EXPORT_SYMBOL_GPL_ONLY" or "...ONLY UNDER_GPL" would make the
meaning clearer, but I don't really think the gain is worth the pain.
Anybody using kernel interfaces ought to be able to figure it out.
But those symbols aren't, they're about internal interfaces that might
change.
Folks who think this is likely to make a difference in court might
want to look at
<http:www.linuxworld.com/news/2006/120806-closed-modules2.html> for a
litany of court cases that have rejected infringement claims where a
much sterner effort had been made to hide or block use of interfaces.
The article claims that courts have increasingly found that
interfacing your code to an existing work is not infringement,
regardless of what you have to work around to do it.
Of course, that's one author's reading of the case law and I'm sure
there are others who disagree, but it's something you'd want to keep
in mind in calculating the expected value of a suit...
