Hello, again.

Yeah, now I'm fairly sure I was spewing out complete bullshit.  Sorry
about that.  Gees, why does spewing out bullshit always feel so right?
Please feel free to call me an idiot.  Can you please try the
following patch and see whether it changes the module counting
behavior?

Thanks.

To which tree shall I apply it? It currently fails both on Linus'
linux-2.6 and
git://git.kernel.org/pub/scm/linux/kernel/git/tj/libata-dev.git .

Hmm... weird.  It's against Linus' tree.  Checking, yeap, it applies
cleanly to 2.6.36-rc4, commit 2422084a (Merge branch 'for-linus' of
git://git.kernel.org/pub/scm/linux/kernel/git/mattst88/alpha-2.6).

Thanks.
