nathanchance added a comment.
This commit causes some warnings in the Linux kernel that appear to be false
positives. For example:
CC drivers/base/cpu.o
drivers/base/cpu.c:404:1: error: control may reach end of non-void function
[-Werror,-Wreturn-type]
}
^
1 error generated.
Corresponds to this function
<https://github.com/torvalds/linux/blob/v5.3-rc6/drivers/base/cpu.c#L398-L404>:
struct device *get_cpu_device(unsigned cpu)
{
if (cpu < nr_cpu_ids && cpu_possible(cpu))
return per_cpu(cpu_sys_devices, cpu);
else
return NULL;
}
creduce spits out:
a() {
if (b())
return ({
while (0)
;
0;
});
else
return 0;
}
