Discomfort? Not really, sorry if my stubbornness felt like it. No, I'm
fine with it.
I just thought it was weird the change of behaviour from 2.6.32, plus
felt that the "Used by" field by lsmod was incorrectly set at 0 since
the module is, in fact, being used (e)
If you say both behaviours are expected and preferred, besides being
consistent with other modules (something I didn't know), I really can't
argue any more.
Thanks for the explanation and sorry for the noise :)
