Hmm, I thought Documentation/ABI/ was supposed to tell us what's an
ABI you can depend on and what's not. I mean, you shouldn't be
depending on anything but the interfaces documented in
Documentation/ABI/stable/, no?
Who is the f*cking MORON that thinks that "documentation" has any meaning
what-so-ever?
The fact that something is documented (whether correctly or not) has
absolutely _zero_ impact on anything at all. What makes something an ABI
is that it's useful and available. The only way something isn't an ABI is
by _explicitly_ making sure that it's not available even by mistake in a
stable form for binary use.
Example: kernel internal data structures and function calls. We make sure
that you simply _cannot_ make a binary that works across kernel versions.
That is the only way for an ABI to not form.
