At the risk of sounding snarky - you use INIT_LIST_HEAD when you have
an argument of the type it takes, and you use LIST_INIT_HEAD when you
have something of the type that *that* one takes. Just like math.h gives
us:
double sin(double x);
float sinf(float x);
so if you have a float, you call sinf() and if you have a double, you
call sin().
(Hint: One looks suspiciously like a data initializer, the other looks
like executable code.... :)
