Re: [PATCH] rcu: remove unused variable in boot_cpu_state_init

[Ingo Molnar]

So, to continue this side thought about uninitialized_var(), it is dangerous 
because the following buggy pattern does not generate a compiler warning:

        long uninitialized_var(error);

	...

        if (error)
                return error;


... and still there are over 290 uses of uninitialized_var() in the kernel - and 
any of them could turn into a silent but real uninitialized variable bugs due to 
subsequent changes.

Thanks,
