I miss the prototype for this in a header?
Prototype is not really necessary for this. Hence not added.
There is a simple rule:
1) If a function is declared => not static
2) If function not declared => static
With respect to this simple rule your functions shall be defined as static.
And that would not work.
Fair enough. Will add prototypes in include/linux/smpboot.h
Thanks you!
