What is the point of this function?

[Andrea Benelli]

Hello, i was looking at the *linux/sched.h* (kernel version 4.6.2) source
code and i found this function at line *1174*:

static inline bool cpus_share_cache(int this_cpu, int that_cpu)
{
        return true;
}

I'm not able to understand the utility of a function that just return a
true value.
i've noticed that there are a lot of functions like this (function that
just return a constant).

so...why?
thanks.
