Yup, shows up on my F16 machine too, with a slightly different gcc version.
gcc --version
gcc (GCC) 4.6.2 20111027 (Red Hat 4.6.2-1)

Egad! This is an old version. It still uses *gasp* logdev!

I have a new version that writes into ftrace, and doesn't use #ifdef,
but instead just looks to see if it is added to the kernel or not.

So no, this patch isn't the fix. The real fix is to upgrade to the new
version of the code.

Of the compiler you mean?

:) Yup, that's what he meant. Of course this is not a realistic option
for many of us. Can you live with the stupid warning for now instead
of cluttering the code with the annotations?

Thanks
