What's the difference between extern and static inline ?

Let Linus explain :

- static inline "means" we have to have this function, if you use it but don't inline it, then make a static version of it in this compilation unit.

- extern inline "means" I actually _have_ an extern for this function, but if you want to inline it, here's the inline-version.

But also see Inline Functions in C
