I think not doing the defn before the caller is nice, but I honestly
could care less either way as far as merging things goes (it seems like
Christoph hates then but people like Jeff let the driver writer do what
they want). Qlogic seems to love doing it, so are they ok with all these
patches?

Is my mailer messing up the tabs or are you (maybe the original code was
messed up and did not get fixed in the move)?
