still getting lots of spam,
but lots nicer after your series.

The key point is that you need to review
each warning if it's a real bug or just a false
positive.
This is not always trivial, I got at least one
wrong in the earlier series (shut up one real bug)

Some are trivial, but then
some require changes i.g.
the variable is removed but the function
requires more than two variables kind of error..
leaving me in a whirlwind with what to put there..
I'll go and try for the easy ones,
first, then(try) and tackle hard ones.

There is no great solution to this, in a fair number of cases the fix would slow
the code or make it harder to read, so some of these probably don't want a fix.
Of course some clearly are errors, so you are doing something valuable by checking.

cool thanks..
I'm guessing lots
of false positives then.
I'll go through and see what
I find..

Sorry that's wrong: the optimizer will generate the same
code anyways as if the unused variable was not there
because it eliminates unused variables.
So fixing this cannot make code slower.
I also don't see how unused variables make the code easier
to read.
The only difficult case sometimes is with #ifdef code,
that has to be handled case by case. One elegant solution
is to replace the ifdef code with an inline.

All warnings should be fixed, I only left those in that
are real code bugs if I couldn't fix the code.
Kernel builds are expected to be relatively warning free
so that you can easily spot new warnings.
But eventually someone who knows the code better has to
fix that bug.

If one puts an 'if' around the variable set (I've seen it) the test may
well take longer than the assign, assuming that there's a case where the
assign is done.

No, my point was that putting a bunch of ifdef statements in to avoid
the warning will make the code harder to read.
