<p dir="ltr">Hello, i was looking at the <i>linux/sched.h</i> (kernel version 4.6.2) source code and i found this function at line <b>1174</b>: </p>
<p dir="ltr">static inline bool cpus_share_cache(int this_cpu, int that_cpu)<br>
{<br>
return true;<br>
}</p>
<p dir="ltr">I'm not able to understand the utility of a function that just return a true value. <br>
i've noticed that there are a lot of functions like this (function that just return a constant). </p>
<p dir="ltr">so...why? <br>
thanks.<br>
