@penguin42 I am absolutely staggered that there are no lint or validation tools that could identify dead code paths and unused variables.

Even worse, the fact that such checks are not a pre-req for a Linux kernel release.

I am pretty sure 'gcc -Wall' did so.

@andyc Neither gcc or clang warn on at least some of the ones I'm finding; while they'll complain about an unused variable, they won't complain about an unused struct definition; there are also some cases where it won't complain about unused static's - in the weird way I tripped over. People do run lots of scanning tools - and one thing I'm hoping from this mail is if someone comes along and says 'Oh yeh, we could add a check to ....'

@andyc I've just posted a gcc bug request for one of the cases; I have sympathy it's not so much a bug as such since the value is kind of used:

@dick_turpin I was hoping for less painful thoughts.

@penguin42 I'm surprised you didn't reply "More intelligent thoughts"?

@dick_turpin Well I wasn't going to expect them from you was I?

@penguin42 TaDa!
